Set the model objective

set_objective(model, expression, sense = c("max", "min")) set_objective_(model, expression, sense = c("max", "min"))

model | the model |
---|---|

expression | the linear objective as a sum of variables and constants |

sense | the model sense. Must be either "max" or "min". |
