A string of up to 200 characters containing the problem name.

Character array containing the row types:

Array containing the right hand side coefficients of the rows. The right hand side value for a range row gives the upper bound on the row.

Array containing the range values for range rows. Values for all other rows will be ignored. May be None 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.

Array containing the objective function coefficients.

Array containing the offsets in the mrwind and dmatval arrays of the start of the elements for each column. This array is of length equal to the number ncol of added variables or, if mnel is None, ncol+1. If mnel is None the extra entry of mstart, mstart[ncol], contains the position in the mrwind and dmatval arrays at which an extra column would start, if it were present.

Array containing the number of nonzero elements in each column. May be None if all elements are contiguous and mstart[ncol] contains the offset where the elements for column ncol+1 would start. This array is not required if the non-zero coefficients in the mrwind and dmatval arrays are continuous, and the mstart array has ncol+1 entries as described above. It may be None if not required.

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 mrwind is mstart[ncol-1]+mnel[ncol-1] or, if mnel is None, mstart[ncol].

Array containing the nonzero element values; length as for mrwind.

Array containing the lower bounds on the columns. Use -xpress.infinity to represent a lower bound of minus infinity.

Array containing the upper bounds on the columns. Use xpress.infinity to represent an upper bound of plus infinity.

(optional) Array with the first variable in each quadratic term.

(optional) Array with the second variable in each quadratic term.

(optional) Array with the quadratic coefficients.

(optional) Integer containing the indices of rows with quadratic matrices in them. Note that the rows are expected to be defined in qrtype as type L.

(optional) Array containing the number of nonzeros in each quadratic constraint matrix.

(optional) Array with a number of elements equal to the sum of the elements in qcnquads (i.e. the total number of quadratic matrix elements in all the constraints). It contains the first column indices of the quadratic matrices. Indices for the first matrix are listed from 0 to qcnquads[0]-1, for the second matrix from qcnquads[0] to qcnquads[0]+ qcnquads[1]-1, etc.

(optional) Array containing the second index for the quadratic constraint matrices.

(optional) Array containing the coefficients for the quadratic constraint matrices.

Character array containing the entity types:

(optional) Array containing the variables of the global entities.

(optional) Array 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 None if not required.

(optional) Character array of length equal to the number of sets specified, problem.attributes.nsets, and specifies the set types:

May be None if not required.

(optional) Array containing the offsets in the mscols and dref 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 None if not required.

(optional) Array of length msstart[nsets]-1 containing the columns in each set. May be None if not required.

(optional) Array of length msstart[nsets]-1 containing the reference row entries for each member of the sets. May be None if not required.

(optional) Array of containing the column names for all variables added.

(optional) Array of containing the row names for all constraints added.
