CPXcrushx

int CPXPUBLIC CPXcrushx(CPXCENVptr env, CPXCLPptr lp, const double * x, double * prex)
Definition file: cplex.h
Include files: cplex.h
Note

This is an advanced routine. Advanced routines typically demand a profound 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 CPXcrushx crushes a solution for the original problem to a solution for the presolved problem.

Example

 status = CPXcrushx (env, lp, origx, reducex);

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

prex

An array to receive the primal values corresponding to the presolved problem. The array must be of length at least the number of columns in the presolved problem object.

Returns:

The routine returns zero on success and nonzero if an error occurs.
