solutionCPLEX: Access Solution Values Produced by Optimization Routines

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

Description

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

Usage

  solutionCPLEX(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 solution which calls the CPLEX function CPXsolution.

Value

If successful a list is returned:

lpstat	result of the optimization
objval	objective function value
x	values of the variables for the problem
pi	values of the dual variables
slack	values of the slack or surplus variables
dj	values of the reduced costs

otherwise an instance of class "cplexError".
