changeObjCoefs-methods

Change Column (Variable) Objective Coefficients in the Optimization Problem

Description

Change column (variable) objective coefficients in the optimization problem.

Usage

## S4 method for signature 'optObj_clpAPI'
changeObjCoefs(lp, j, obj_coef)

## S4 method for signature 'optObj_cplexAPI'
changeObjCoefs(lp, j, obj_coef)

## S4 method for signature 'optObj_glpkAPI'
changeObjCoefs(lp, j, obj_coef)

## S4 method for signature 'optObj_lpSolveAPI'
changeObjCoefs(lp, j, obj_coef)

Arguments

`lp`	An object extending class `optObj`.
`j`	A numeric vector containing the column indices of the variables to change.
`obj_coef`	A numeric vector of the same length as `j` containing the objective coefficients of the variables to change.

Methods

signature(lp = "optObj_clpAPI"): method to use with package optObj_clpAPI.
signature(lp = "optObj_cplexAPI"): method to use with package optObj_cplexAPI.
signature(lp = "optObj_glpkAPI"): method to use with package optObj_glpkAPI.
signature(lp = "optObj_lpSolveAPI"): method to use with package optObj_lpSolveAPI.
