# get_var_priority Returns, for the specified variable, the priority the variable has in the branch-and-bound algorithm. int get_var_priority(lprec *lp, int column); Return Value get_var_priority returns the priority of the variable. 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 column The column number of the variable on which the priority must be returned. It must be between 1 and the number of columns in the lp. If it is not within this range, the return value is 0 Remarks The get_var_priority function returns the priority the variable has in the branch-and-bound algorithm. This priority is determined by the weights set by set_var_weights. The default priorities are the column positions of the variables in the model. Example
    #include <stdio.h>
    #include <stdlib.h>
    #include "lp_lib.h"

    int main(void)
    {
      lprec *lp;
      REAL weights[2];
      int priority;

      /* Create a new LP model */
      lp = make_lp(0, 2);
      if(lp == NULL) {
        fprintf(stderr, "Unable to create new LP model\n");
        return(1);
      }

      weights[0] = 2;
      weights[1] = 1;

      set_var_weights(lp, weights);

      priority = get_var_priority(lp, 1); /* will return 2 */
      priority = get_var_priority(lp, 2); /* will return 1 */

      delete_lp(lp);
      return(0);
    }
