XPRSgetpoolsolution

Purpose
Returns the primal values of a solution collected in the solution pool after optimization with XPRSoptimize, XPRSmipoptimize, XPRSlpoptimize or XPRSnlpoptimize.
Topic areas
Solution, Solution Pool
Synopsis
int XPRSgetpoolsolution(XPRSprob prob, int num, int *status, double x[], int first, int last);
Arguments
prob 
The current problem.
num 
The index of the solution in the pool. Should be a value from 0 to POOLSIZE -1.
status 
Returned as XPRS_SOLAVAILABLE_NOTFOUND ( 0) if no solution with index num is found, otherwise returned as XPRS_SOLAVAILABLE_FEASIBLE ( 2).
x 
Double array of length last-first+1 where the value of the primal variables will be returned. May be NULL if not required.
first 
First column in the solution.
last 
Last column in the solution.
Example
See also example solution_pool.c.
Further information
1. The function always returns data in the input space, even if the problem is currently in presolved state. Column indices should be in the range 0 to INPUTCOLS- 1.
2. This function can not be called from within callbacks.
3. Solutions are ordered from best to worst objective value, so index 0 corresponds to the solution with the best objective value found.
