CPXXreadcopyorder and CPXreadcopyorder

The routine CPXXreadcopyorder/CPXreadcopyorder reads an ORD file and copies the priority order information into a CPLEX problem object.

int CPXXreadcopyorder( CPXCENVptr env, CPXLPptr lp, char const * filename_str )

int CPXreadcopyorder( CPXCENVptr env, CPXLPptr lp, char const * filename_str )

Description

The routine CPXXreadcopyorder/CPXreadcopyorder reads an ORD file and copies the priority order information into a CPLEX problem object. The MIP priority order switch (CPXPARAM_MIP_Strategy_Order parameter) must be set to CPX_ON (its default value), in order for the priority order to be used for starting a subsequent optimization.

Arguments

env: A pointer to the CPLEX environment as returned by CPXXopenCPLEX/CPXopenCPLEX.
lp: A pointer to a CPLEX problem object as returned by CPXXcreateprob/CPXcreateprob.
filename_str: The name of the file from which the priority order should be read.

Return

The routine returns 0 (zero) if successful and nonzero if an error occurs.

Example


 status = CPXreadcopyorder (env, lp, "myprob.ord");
