Set the model objective — set_objective • ompr

Set the model objective

set_objective(model, expression, direction = c("max", "min"))

set_objective_(model, expression, direction = c("max", "min"))

Arguments

model: the model
expression: the linear objective as a sum of variables and constants
direction: the optimization direction. Must be either "max" or "min".

Value

a Model with a new objective function definition

Examples

library(magrittr)
MIPModel() %>%
 add_variable(x, lb = 2) %>%
 add_variable(y, lb = 40) %>%
 set_objective(x + y, direction = "min")
#> Mixed linear integer optimization problem
#> Variables:
#>   Continuous: 2 
#>   Integer: 0 
#>   Binary: 0 
#> Search direction: minimize 
#> Constraints: 0
