CPXuncrushx

public int CPXuncrushx(CPXCENVptr env, CPXCLPptr lp, double * x, const double * prex)
Definition file: cplex.h
Note

This is an advanced routine. Advanced routines typically demand a thorough understanding of the algorithms used by ILOG CPLEX. Thus they incur a higher risk of incorrect behavior in your application, behavior that can be difficult to debug. Therefore, ILOG encourages you to consider carefully whether you can accomplish the same task by means of other Callable Library routines instead.

The routine CPXuncrushx uncrushes a solution for the presolved problem to the solution for the original problem.

Example

 status = CPXuncrushx (env, lp, x, prex);

Parameters:

env

A pointer to the CPLEX environment, as returned by CPXopenCPLEX.

lp

A pointer to a CPLEX LP problem object, as returned by CPXcreateprob.

x

An array to receive the primal solution (x) values for the original problem as computed from primal values of the presolved problem object. The array must be of length at least the number of columns in the LP problem object.

prex

An array that contains primal solution (x) values for the presolved problem, as returned by routines such as CPXgetx and CPXsolution when applied to the presolved problem object. The array must be of length at least the number of columns in the presolved problem object.

Returns:

The routine returns zero if successful and nonzero if an error occurs.
