refineMIPstartConflictExtCPLEX: Identify a Minimal Conflict

Description

Low level interface function to the IBM ILOG CPLEX function CPXrefinemipstartconflictext. Consult the IBM ILOG CPLEX documentation for more detailed information.

Usage

refineMIPstartConflictExtCPLEX(env, lp, mipstartindex, grpcnt, concnt,
                                 grppref, grpbeg, grpind, grptype)

Arguments

env

An object of class "'>cplexPtr" as returned by openEnvCPLEX. This is basically a pointer to an IBM ILOG CPLEX environment.

lp

An object of class "'>cplexPtr" as returned by initProbCPLEX. This is basically a pointer to an IBM ILOG CPLEX problem object.

mipstartindex

The index of the MIP start.

grpcnt

The number of constraint groups to be considered.

concnt

Length of arrays grpind and grptype.

grppref

Preferences for the groups.

grpbeg

The constraint indices. Consult the IBM ILOG CPLEX documentation for more detailed information.

grpind

The constraint indices. Consult the IBM ILOG CPLEX documentation for more detailed information.

grptype

The constraint indices. Consult the IBM ILOG CPLEX documentation for more detailed information.

Value

Zero if successful, otherwise nonzero.

Details

Interface to the C function refineMIPstartConflictExt which calls the CPLEX function CPXrefinemipstartconflictext.
