feasOptCPLEX: Compute a Minimum-Cost Relaxation

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

Description

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

Usage

  feasOptCPLEX(env, lp, rhs = FALSE, rng = FALSE, lb = FALSE, ub = FALSE)

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.
rhs	If set to FALSE no right hand side value is allowed to be relaxed.
rng	If set to FALSE no range values are allowed to be relaxed.
lb	If set to FALSE no lower bound of any variable is allowed to be relaxed.
ub	If set to FALSE no lower bound of any variable is allowed to be relaxed.

Details

Interface to the C function feasOpt which calls the CPLEX function CPXfeasopt.

Value
