CPXgetcrossdexchcnt

int CPXPUBLIC CPXgetcrossdexchcnt(CPXCENVptr env, CPXCLPptr lp)

Definition file: cplex.h

Include files: cplex.h

The routine CPXgetcrossdexchcnt is used to access the number of dual 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.

Example

 itcnt = CPXgetcrossdexchcnt (env, lp);

Parameters:

env	A pointer to the CPLEX environment as returned by `CPXopenCPLEX`.
lp	A pointer to a CPLEX problem object as returned by `CPXcreateprob`. Example itcnt = CPXgetcrossdexchcnt (env, lp);

Returns:

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