Expand description

Trait to be implemented on ModelMeta data.

Required Methods§

Source

fn get_pattern_vars(&mut self) -> &mut HashMap<ColumnId, Var>

Return the column selection decision variables

Provided Methods§

Source

fn callback_before_optimize( &mut self, lower_bound: f64, best_known: &RwLock<(f64, Vec<(f64, ColumnId)>)>, model: &mut Model, )

Callback that is called just prior to optimizing the LP model Can be used to make custom modifications
