Constructor Detail
- XPRSprob
```
public XPRSprob()
         throws XPRSprobException
```
  Creates a new, empty problem. Note that instances of this class should be explicitly cleaned up by calling close() so that native resources can be released and licenses can be released. A good practice is to use instances of this class with try-with-resources.
  
  Throws:
  
  XPRSprobException - if the problem cannot be created.
- XPRSprob
```
public XPRSprob(java.lang.String path)
         throws XPRSprobException,
                XPRSexception
```
  Creates a new, empty problem. The functions calls XPRS.init(path) so you don't have to do that explicitly. Problems constructed this way will also take care of calling XPRS.free() to match the call to XPRS.init() made from this constructor. Note that instances of this class should be explicitly cleaned up by calling close() so that native resources can be released and licenses can be released. A good practice is to use instances of this class with try-with-resources.
  
  Parameters:
  
  path - The path to the license location for XPRS.init. This can be code null.
  
  Throws:
  
  XPRSexception - if the license cannot be initialized.
  
  XPRSprobException - if the problem cannot be created.
  
  Since:

             nrows - Number of rows in the matrix (not including the objective). Objective coefficients must be supplied in the 
             objcoef array, and the objective function should not be included in any of the other arrays.
             
            
             rowtype - Character array of length 
             nrows containing the row types: 
             
              L: indicates a <= constraint;

             rhs - Double array of length 
             nrows containing the right hand side coefficients of the rows. The right hand side value for a range row gives the

             rng - Double array of length 
             nrows containing the range values for range rows. Values for all other rows will be ignored. May be 
             null if not required. The lower bound on a range row is the right hand side value minus the range value. The sign of the range value is ignored - the absolute value is used in all cases.
             
            
             objcoef - Double array of length 
             ncols containing the objective function coefficients.

             rowind and 
             rowcoef arrays at which an extra column would start, if it were present. In C, this value is also the length of the 
             rowind and 
             rowcoef arrays.
             
            
             collen - Integer array of length 
             ncols containing the number of nonzero elements in each column. May be

             rowind and 
             rowcoef arrays are continuous, and the 
             start array has 
             ncols+1 entries as described above.
             
            
             rowind - Integer array containing the row indices for the nonzero elements in each column. If the indices are input contiguously, with the columns in ascending order, the length of the 
             rowind is 
             start[ncols-1]+collen[ncols-1] or, if 
             collen is 
             null, 
             start[ncols].
             
            
             rowcoef - Double array containing the nonzero element values; length as for 
             rowind.
             
            
             lb - Double array of length 
             ncols containing the lower bounds on the columns. Use 
             XPRS_MINUSINFINITY to represent a lower bound of minus infinity.
             
            
             ub - Double array of length 
             ncols containing the upper bounds on the columns. Use 
             XPRS_PLUSINFINITY to represent an upper bound of plus infinity.

            Used to load a MIQP problem, hence a MIP with quadratic objective coefficients, into the Optimizer data structures. Integer, binary, partial integer, semi-continuous and semi-continuous integer variables can be defined, together with sets of type 1 and 2. The reference row values for the set members are passed as an array rather than specifying a reference row.
            
            
            
             Parameters:
             
            
             probname - A string of up to 
             MAXPROBNAMELENGTH characters containing a name for the problem.
             
            
             ncols - Number of structural columns in the matrix.
             
            
             nrows - Number of rows in the matrix (not including the objective). Objective coefficients must be supplied in the 
             objcoef array, and the objective function should not be included in any of the other arrays.
             
            
             rowtype - Character array of length 
             nrows containing the row type: 
             
              L: indicates a <= constraint; 
              E: indicates an = constraint; 
              G: indicates a >= constraint; 
              R: indicates a range constraint; 
              N: indicates a nonbinding constraint. 
             
             
            
             rhs - Double array of length 
             nrows containing the right hand side coefficients. The right hand side value for a range row gives the 
             upper bound on the row.
             
            
             rng - Double array of length 
             nrows containing the range values for range rows. The values in the range array will only be read for 
             R type rows. The entries for other type rows will be ignored. May be 
             null if not required. The lower bound on a range row is the right hand side value minus the range value. The sign of the range value is ignored - the absolute value is used in all cases.
             
            
             objcoef - Double array of length 
             ncols containing the objective function coefficients.

             rowind and 
             rowcoef arrays of the start of the elements for each column. This array is of length

             rowind and 
             rowcoef arrays are continuous, and the 
             start array has 
             ncols+1 entries as described above. It may be 
             null if not required.
             
            
             rowind - Integer arrays containing the row indices for the nonzero elements in each column. If the indices are input contiguously, with the columns in ascending order, then the length of 
             rowind is 
             start[ncols-1]+collen[ncols-1] or, if 
             collen is 
             null, 
             start[ncols].
             
            
             rowcoef - Double array containing the nonzero element values length as for 
             rowind.

             ub - Double array of length 
             ncols containing the upper bounds on the columns. Use

            Used to load a MIP problem into the Optimizer data structures. Integer, binary, partial integer, semi-continuous and semi-continuous integer variables can be defined, together with sets of type 1 and 2. The reference row values for the set members are passed as an array rather than specifying a reference row.
            
            
            
             Parameters:
             
            
             probname - A string of up to 
             MAXPROBNAMELENGTH characters containing a name for the problem.

             nrows - Number of rows in the matrix not (including the objective row). Objective coefficients must be supplied in the 
             objcoef array, and the objective function should not be included in any of the other arrays.
             
            
             rowtype - Character array of length 
             nrows containing the row types: 
             
              L: indicates a <= constraint; 
              E: indicates an = constraint; 
              G: indicates a >= constraint;

              N: indicates a nonbinding constraint. 
             
             
            
             rhs - Double array of length 
             nrows containing the right hand side coefficients. The right hand side value for a range row gives the 
             upper bound on the row.
             
            
             rng - Double array of length 
             nrows containing the range values for range rows. Values for all other rows will be ignored. May be 
             null if not required. The lower bound on a range row is the right hand side value minus the range value. The sign of the range value is ignored - the absolute value is used in all cases.
             
            
             objcoef - Double array of length 
             ncols containing the objective function coefficients.

             rowind and 
             rowcoef arrays of the start of the elements for each column. This array is of length 
             ncols or, if 
             collen is 
             null, length

             rowind and 
             rowcoef arrays at which an extra column would start, if it were present. In C, this value is also the length of the 
             rowind and 
             rowcoef arrays.
             
            
             collen - Integer array of length 
             ncols containing the number of nonzero elements in each column. May be

             rowind and 
             rowcoef arrays are continuous, and the 
             start array has 
             ncols+1 entries as described above. It may be 
             null if not required.
             
            
             rowind - Integer arrays containing the row indices for the nonzero elements in each column. If the indices are input contiguously, with the columns in ascending order, then the length of 
             rowind is 
             start[ncols-1]+collen[ncols-1] or, if 
             collen is 
             null, 
             start[ncols].
             
            
             rowcoef - Double array containing the nonzero element values length as for 
             rowind.
             
            
             lb - Double array of length 
             ncols containing the lower bounds on the columns. Use 
             XPRS_MINUSINFINITY to represent a lower bound of minus infinity.
             
            
             ub - Double array of length 
             ncols containing the upper bounds on the columns. Use 
             XPRS_PLUSINFINITY to represent an upper bound of plus infinity.
             
            
             nentities - Number of binary, integer, semi-continuous, semi-continuous integer and partial integer entities.

             coltype - Character array of length 
             nentities containing the entity types: 
             
              B: binary variables;

             limit - Double array of length 
             nentities containing the integer limits for the partial integer variables and lower bounds for semi-continuous and semi-continuous integer variables (any entries in the positions corresponding to binary and integer variables will be ignored). May be 
             null if not required.
             
            
             settype - Character array of length 
             nsets containing the set types: 
             
              1: SOS1 type sets; 
              2: SOS2 type sets.
             May be 
             null if not required.
             
            
             setstart - Integer array containing the offsets in the 
             setind and 
             refval arrays indicating the start of the sets. This array is of length 
             nsets+1, the last member containing the offset where set 
             nsets+1 would start. May be 
             null if not required.
             
            
             setind - Integer array of length 
             setstart[nsets]-1 containing the columns in each set. May be 
             null if not required.
             
            
             refval - Double array of length 
             setstart[nsets]-1 containing the reference row entries for each member of the sets. These define the order for SOS2 constraints and may be used in branching for both types. May be

                   throws XPRSprobException 
           
            Specifies that a set of rows in the matrix will be treated as indicator constraints during a tree search. An indicator constraint is made of a 
            condition and a 
            constraint. The 
            condition is of the type "
            bin = value", where 
            bin is a binary variable and 
            value is either 0 or 1. The 
            constraint is any matrix row (may be linear, quadratic or general nonlinear). During tree search, a row configured as an indicator constraint is enforced only when condition holds, that is only if the indicator variable 
            bin has the specified value. Note that every row may only get assigned a single indicator variable and term. If a row needs to be activated by multiple different terms, the row needs to be duplicated so that each term can be assigned to a distinct row. If the indicator variable should be changed, the old term needs to be deleted first (by calling 
            delIndicators or by calling this function with a comps argument of 0) before assigning a new one.
            
            
            
             Parameters:
             
            
             nrows - The number of indicator constraints.
             
            
             rowind - Integer array of length 
             nrows containing the indices of the rows that define the constraint part for the indicator constraints.
             
            
             colind - Integer array of length 
             nrows containing the column indices of the indicator variables.
             
            
             complement - Integer array of length 
             nrows with the complement flags: 
             
              0: not an indicator constraint (in this case the corresponding entry in the colind array is ignored);  
              1: for indicator constraints with condition "bin = 1"; 
              -1: for indicator constraints with condition "bin = 0".

            y = f(x) consists of an (input) column x, a (different) resultant (output column) y and a piecewise linear function f.

Discontinuous piecewise linear functions are supported, in this case both the left and right limit at a given point need to be entered as breakpoints. To differentiate between left and right limit, the breakpoints need to be given as a list with non-decreasing x-values.

            Used to load a mixed integer quadratic problem with quadratic constraints into the Optimizer data structure. Such a problem may have quadratic terms in its objective function as well as in its constraints. Integer, binary, partial integer, semi-continuous and semi-continuous integer variables can be defined, together with sets of type 1 and 2. The reference row values for the set members are passed as an array rather than specifying a reference row.
            
            
            
             Parameters:
             
            
             probname - A string of up to 
             MAXPROBNAMELENGTH characters containing a name for the problem.
             
            
             ncols - Number of structural columns in the matrix.
             
            
             nrows - Number of rows in the matrix (not including the objective row). Objective coefficients must be supplied in the 
             objcoef array, and the objective function should not be included in any of the other arrays.
             
            
             rowtype - Character array of length 
             nrows containing the row types: 
             
              L: indicates a <= constraint (use this one for quadratic constraints as well); 
              E: indicates an = constraint; 
              G: indicates a >= constraint;  
              R: indicates a range constraint; 
              N: indicates a nonbinding constraint. 
             
             
            
             rhs - Double array of length 
             nrows containing the right hand side coefficients of the rows. The right hand side value for a range row gives the

             rng - Double array of length 
             nrows containing the range values for range rows. Values for all other rows will be ignored. May be null if there are no ranged constraints. The lower bound on a range row is the right hand side value minus the range value. The sign of the range value is ignored - the absolute value is used in all cases.
             
            
             objcoef - Double array of length 
             ncols containing the objective function coefficients.

             rowind and 
             rowcoef arrays of the start of the elements for each column. This array is of length 
             ncols or, if 
             collen is null, 
             length ncols+1. If

             rowcoef arrays at which an extra column would start, if it were present. In C, this value is also the length of the 
             rowind and 
             rowcoef arrays.

             ncols+1 would start. This array is not required if the non-zero coefficients in the 
             rowind and 
             rowcoef arrays are continuous, and the 
             start array has

             collen is null, 
             start[ncols].
             
            
             rowcoef - Double array containing the nonzero element values; length as for 
             rowind.

             ub - Double array of length 
             ncols containing the upper bounds on the columns. Use 
             XPRS_PLUSINFINITY to represent an upper bound of plus infinity.
             
            
             nobjqcoefs - Number of quadratic terms.

             0 to 
             nrowqcoefs[0]-1, for the second matrix from

             Parameters:
             
            
             probname - A string of up to 
             MAXPROBNAMELENGTH characters containing a name for the problem.

             nrows - Number of rows in the matrix (not including the objective row). Objective coefficients must be supplied in the 
             objcoef array, and the objective function should not be included in any of the other arrays.
             
            
             rowtype - Character array of length

            Returns the nonzeros in the quadratic objective coefficients matrix for the columns in a given range. To achieve maximum efficiency, 
            getMQObj returns the lower triangular part of this matrix only.
            
            
            
             Parameters:
             
            
             start - Integer array which will be filled with indices indicating the starting offsets in the 
             colind and 
             objqcoef arrays for each requested column. It must be length of at least 
             last-first+2. Column 
             i starts at position 
             start[i] in the 
             mrwind and 
             dmatval arrays, and has 
             start[i+1]-start[i] elements in it. May be null if 
             maxcoefs is 
             0.
             
            
             colind - Integer array of length 
             maxcoefs which will be filled with the column indices of the nonzero elements in the lower triangular part of 
             Q. May be 
             null if 
             maxcoefs is 
             0.
             
            
             objqcoef - Double array of length 
             maxcoefs which will be filled with the nonzero element values. May be 
             null if 
             maxcoefs is 
             0.
             
            
             maxcoefs - The maximum number of elements to be returned (size of the arrays).
             
            
             p_ncoefs - Pointer to an integer where the number of nonzero quadratic objective coefficients will be returned. If the number of nonzero coefficients is greater than 
             maxcoefs, then only 
             maxcoefs elements will be returned. If 
             p_ncoefs is smaller than 
             maxcoefs, then only 
             p_ncoefs will be returned.
             
            
             first - First column in the range.
             
            
             last - Last column in the range.

            Adds cuts directly to the matrix at the current node. Any cuts added to the matrix at the current node and not deleted at the current node will be automatically added to the cut pool. The cuts added to the cut pool will be automatically restored at descendant nodes.
            
            
            
             Parameters:
             
            
             ncuts - Number of cuts to add.
             
            
             cuttype - Integer array of length 
             ncuts containing the user assigned cut types. The cut types can be any integer chosen by the user, and are used to identify the cuts in other cut manager routines using user supplied parameters. The cut type can be interpreted as an integer or a bitmap - see 
             delCuts.
             
            
             rowtype - Character array of length 
             ncuts containing the row types: 
             
              L: indicates a <= row; 
              G: indicates a >= row; 
              E: indicates an = row. 
             
             
            
             rhs - Double array of length 
             ncuts containing the right hand side elements for the cuts.
             
            
             start - Integer array containing offset into the 
             colind and 
             cutcoef arrays indicating the start of each cut. This array is of length 
             ncuts+1 with the last element, 
             start[ncuts], being where cut 
             ncuts+1 would start.
             
            
             colind - Integer array of length 
             start[ncuts] containing the column indices in the cuts.
             
            
             cutcoef - Double array of length 
             start[ncuts] containing the matrix values for the cuts.

            Deletes cuts from the matrix at the current node. Cuts from the parent node which have been automatically restored may be deleted as well as cuts added to the current node using 
            addCuts or 
            loadCuts. The cuts to be deleted can be specified in a number of ways. If a cut is ruled out by any one of the criteria it will not be deleted.
            
            
            
             Parameters:
             
            
             basis - Ensures the basis will be valid if set to 
             1. If set to 
             0, cuts with non-basic slacks may be deleted.
             
            
             cuttype - User defined type of the cut to be deleted.
             
            
             interp - Way in which the cut 
             cuttype is interpreted: 
             
              -1: match all cut types; 
              1: treat cut types as numbers; 
              2: treat cut types as bit maps - delete if any bit matches any bit set in cuttype; 
              3: treat cut types as bit maps - delete if all bits match those set in cuttype. 
             
             
            
             delta - Only delete cuts with an absolute slack value greater than 
             delta. To delete all the cuts, this argument should be set to 
             XPRS_MINUSINFINITY.
             
            
             ncuts - Number of cuts to drop if a list of cuts is provided. A value of 
             -1 indicates all cuts.
             
            
             cutind - Array containing pointers to the cuts which are to be deleted. This array may be 
             null if 
             ncuts is set to 
             -1 otherwise it has length 
             ncuts.

            throws XPRSprobException 
           
            Appends an objective function with the given coefficients to a multi-objective problem. The weight and priority of the objective are set to the given values.
            
            
            
             Parameters:
             
            
             ncols - Number of objective function coefficient elements to add.
             
            
             colind - Integer array of length 
             ncols containing the indices of the columns whose objective coefficients will change. An index of 
             -1 indicates that the fixed part of the objective function on the right hand side should change.
             
            
             objcoef - Double array of length 
             ncols giving the new objective function coefficients.
             
            
             priority - The priority for the objective function. During optimization, objectives with the same priority are combined together in a weighted sum.
             
            
             weight - The weight for the objective function. If the weight is negative, the sense of this objective is reversed.

             throws XPRSprobException 
           
            Modifies one or more coefficients of an objective function in a multi-objective problem. If the objective already exists, any coefficients not present in the 
            colind and 
            objcoef arrays will unchanged. If the objective does not exist, it will be added to the problem.
            
            
            
             Parameters:
             
            
             objidx - Index of the objective function to add or modify.
             
            
             ncols - Number of objective function coefficient elements to change.

           delObj
 public void delObj(int objidx)
            throws XPRSprobException 
           
            Removes an objective function from a multi-objective problem. Any objectives with 
            index > objidx will be shifted down. Deleting the last objective function in the problem causes all the objective coefficients to be zeroed, but 
            OBJECTIVES remains set to 
            1.
