CPXgetcrosspexchcnt

Description

The routine CPXgetcrosspexchcnt() is used to access the number of primal exchange iterations in the crossover method. An exchange occurs when a nonbasic variable is forced to enter the basis as it is pushed toward a bound.

The routine returns the primal exchange iteration count if a solution exists. If no solution exists, it returns a zero.

int CPXgetcrosspexchcnt (CPXCENVptr env, CPXCLPptr lp);

Arguments

The pointer to the CPLEX environment as returned by CPXopenCPLEX().

A pointer to a CPLEX problem object as returned by CPXcreateprob().

itcnt = CPXgetcrosspexchcnt (env, lp);
