CPXXreadcopybase and CPXreadcopybase

The routine CPXXreadcopybase/CPXreadcopybase reads a basis from a BAS file, and copies that basis into a CPLEX problem object.

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

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

Description

The routine CPXXreadcopybase/CPXreadcopybase reads a basis from a BAS file, and copies that basis into a CPLEX problem object. The parameter known as the advanced start switch (CPXPARAM_Advance) must be set to 1 (one), its default value, or 2 (two) in order for the basis 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 basis should be read.

Return

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

Example


status = CPXreadcopybase (env, lp, "myprob.bas");
