XPRSgetcallbacksolution
Purpose
Returns the solution associated with the current callback.
Synopsis
int XPRS_CC XPRSgetcallbacksolution(XPRSprob prob, int *p_available, double x[], int first, int last);
Arguments
|
prob
|
The current problem.
|
|
p_available
|
This variable will be set to 1 if a solution is available. May be NULL if not required.
|
|
x
|
Double array of length
last-first+1 where the values of the primal variables will be returned. May be NULL if not required.

|
first
|
First column in the solution to return.
|
|
last
|
