CPXgetsubmethod

int CPXPUBLIC CPXgetsubmethod(CPXCENVptr env, CPXCLPptr lp)

Definition file: cplex.h

Include files: cplex.h

The routine CPXgetsubmethod is used to access the solution method of the last subproblem optimization, in the case of an error termination during mixed integer optimization.

Example

 submethod = CPXgetsubmethod (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 submethod = CPXgetsubmethod (env, lp);

Returns:

The possible return values are summarized below.

Value	Symbolic Constant	Algorithm
0	`CPX_ALG_NONE`	None
1	`CPX_ALG_PRIMAL`	Primal simplex
2	`CPX_ALG_DUAL`	Dual simplex
4	`CPX_ALG_BARRIER`	Barrier optimizer (no crossover)
