XPRSloadlpsol

XPRSloadlpsol

Purpose
Loads an LP solution for the problem into the Optimizer.
Synopsis
int XPRS_CC XPRSloadlpsol(XPRSprob prob, const double x[], const double slack[], const double dual[], const double dj[], int *status);
Arguments
prob 
The current problem.
x 
Optional: Double array of length COLS (for the original problem and not the presolve problem) containing the values of the variables.
slack 
Optional: double array of length ROWS containing the values of slack variables.
dual 
Optional: double array of length ROWS containing the values of dual variables.
dj 
Optional: double array of length COLS containing the values of reduced costs.
status 
Pointer to an int where the status will be returned. The status is one of:
0 
Solution is loaded.
1 
Solution is not loaded because the problem is in presolved status.
Example
This example loads a problem, loads a solution for the problem and then uses XPRScrossoverlpsol to find a basic optimal solution. 

XPRSreadprob(prob, "problem", "");
XPRSloadlpsol(prob, x, NULL, dual, NULL, &status);
XPRScrossoverlpsol(prob, &status);
Further information
1. At least one of variables x and dual variables dual must be provided.
2. When variables x is NULL, the variables will be set to their bounds.
3. When slack variables slack is NULL, it will be computed from variables x. If slacks are provided, variables cannot be omitted.
4. When dual variables dual is NULL, both dual variables and reduced costs will be set to zero.
5. When reduced costs dj is NULL, it will be computed from dual variables dual. If reduced costs are provided, dual variables cannot be omitted.
