refineMIPstartConflictExtCPLEX: Identify a Minimal Conflict

In cplexAPI: R Interface to C API of IBM ILOG CPLEX

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.

Details

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