XPRSgetmipsol

Purpose
Used to obtain the solution values of the last MIP solution that was found.
Synopsis
int XPRS_CC XPRSgetmipsol(XPRSprob prob, double x[], double slack[]);
Arguments
prob 
The current problem.
x 
Double array of length ORIGINALCOLS where the values of the primal variables will be returned. May be NULL if not required.
slack 
Double array of length ORIGINALROWS where the values of the slack variables will be returned. May be NULL if not required.
Example
The following sequence of commands will get the solution ( x) of the last MIP solution for a problem: 
int cols;
double *x;
...
XPRSmipoptimize(prob,"");
XPRSgetintattrib(prob,XPRS_ORIGINALCOLS,&cols);
x = malloc(cols*sizeof(double));
XPRSgetmipsol(prob,x,NULL);

Further information
1. Warning: If allocating space for the MIP solution the row and column sizes must be obtained for the original problem and not for the presolve problem. They can be obtained before optimizing or after calling XPRSpostsolve for the case where the tree search has not completed.
2. During a intsol or preintsol callback, in order to retrieve the corresponding integer solution, use either XPRSgetlpsol or XPRSgetpresolvesol, not XPRSgetmipsol (see the documentation of these callbacks for an explanation).
