problem.postSolve

Purpose
Postsolve the current matrix when it is in a presolved state.
Topic areas
Solution Process, Presolve, Optimizer
Synopsis
problem.postSolve()
Further information
1. A problem is left in a presolved state whenever a LP or MIP optimization does not complete. In these cases problem.postSolve can be called to get the problem back into its original state.
2. For a problem that also went through nonlinear presolve, problem.postSolve by default also invokes problem.nlpPostsolveProb 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.
