Share:

Description

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

Usage

1
  refineConflictCPLEX(env, lp)

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.

Details

Interface to the C function refineConflict which calls the CPLEX function CPXrefineconflict.

Value

If successful a list is returned:

confnumrows

number of linear constraints in the conflict

confnumcols

number of variable bounds in the conflict

otherwise an instance of class "cplexError".
