XPRSloadmipsol

Purpose

Loads a MIP solution for the problem into the optimizer.

Synopsis

int XPRS_CC XPRSloadmipsol(XPRSprob prob, const double dsol[], int *status);

Arguments

prob

The current problem.

dsol

Double array of length COLS (for the original problem and not the presolve problem) containing the values of the variables.

status

Pointer to an int where the status will be returned. The status is one of:

-1

Solution rejected because an error occurred;

0

Solution accepted;

1

Solution rejected because it is infeasible;

2

Solution rejected because it is cut off;

3

Solution rejected because the LP reoptimization was interrupted.

Example

This example loads a problem and then loads a solution found previously for the problem to help speed up the MIP search:
XPRSreadprob(prob,"problem",""):
XPRSloadmipsol(prob,dsol,&status);
XPRSminim(prob,"g");
Further information

The values for the continuous variables in the dsol array are ignored and are calculated by fixing the integer variables and reoptimizing.
