XPRSpostsolvesol

Purpose
Postsolves a primal solution formulated in the presolved space into the corresponding solution formulated in the original space. The problem itself is unchanged.
Topic areas
Solution, Presolve
Synopsis
int XPRS_CC XPRSpostsolvesol(XPRSprob prob, const double prex[], double origx[]);
Arguments
prob 
The current problem.
prex 
Double array of length COLS with the values of the primal variables in the presolved space. Cannot be NULL.
origx 
Double array of length ORIGINALCOLS where the values of the primal variables will be returned. Cannot be NULL.
Further information
This function is useful for advanced users implementing heuristics directly in the presolved space. Once a new solution is obtained, it needs to be mapped to the original space in order to be passed back into the solver.
