changeColsBndsObjCoefs-methods: Change Column (Variable) Bounds and Objective Coefficients in the Optimization Problem

Description

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

Usage

## S3 method for class 'optObj_clpAPI':
changeColsBndsObjCoefs(lp, j, lb, ub, obj_coef)
## S3 method for class 'optObj_cplexAPI':
changeColsBndsObjCoefs(lp, j, lb, ub, obj_coef)
## S3 method for class 'optObj_glpkAPI':
changeColsBndsObjCoefs(lp, j, lb, ub, obj_coef)

Arguments

lp

An object extending class optObj.

j

A numeric vector containing the column indices of the variables to change.

lb

A numeric vector of the same length as j containing the lower bounds of the variables to change.

ub

A numeric vector of the same length as j containing the upper bounds 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.
