get_solutioncount

# get_solutioncount Returns the number of equal solutions. int get_solutioncount(lprec *lp); Return Value get_solutioncount returns the number of equal solutions. This is only valid if there are integer, semi-continious or SOS variables in the model so that the branch-and-bound algoritm is used. This count gives the number of solutions with the same optimal objective value. If there is only one optimal solution, this value is 1. Parameters lp Pointer to previously created lp model. See return value of make_lp, copy_lp, read_lp, read_LP, read_mps, read_freemps, read_MPS, read_freeMPS, read_XLI Remarks The get_solutioncount function returns the number of equal solutions up to get_solutionlimit. Example
    #include <stdio.h>
    #include <stdlib.h>
    #include "lp_lib.h"

    int main(void)
    {
      lprec *lp;
      int solutioncount;

      /* Create a new LP model */
      lp = make_lp(0, 0);
      if(lp == NULL) {
        fprintf(stderr, "Unable to create new LP model\n");
        return(1);
      }

      solve(lp);

      solutioncount = get_solutioncount(lp);

      delete_lp(lp);
      return(0);
    }
