Synopsis
int XPRSpostsolve(XPRSprob prob);
POSTSOLVE
Argument
prob 
The current problem.

Further information
1. A problem is left in a presolved state whenever a LP or MIP optimization does not complete. In these cases XPRSpostsolve ( POSTSOLVE) can be called to get the problem back into its original state.
2. For a problem that also went through nonlinear presolve, XPRSpostsolve by default also invokes XPRSnlppostsolve to restore it all the way back to its original nonlinear form. Set bit 7 of XSLP_CONTROL to disable this and restore only the linear matrix, as in previous releases.
