Member Data Documentation

◆ branch_period

int operations_research::Solver::SearchLogParameters::branch_period = 1

SearchMonitors will display a periodic search log every branch_period branches explored.

Definition at line 2561 of file constraint_solver.h.

◆ display_callback

std::function<std::string()> operations_research::Solver::SearchLogParameters::display_callback

SearchMonitors will display the result of display_callback at each new solution found and when the search finishes if display_on_new_solutions_only is false.

Definition at line 2574 of file constraint_solver.h.

◆ display_on_new_solutions_only

bool operations_research::Solver::SearchLogParameters::display_on_new_solutions_only = true

To be used to protect from cases where display_callback assumes variables are instantiated, which only happens in AtSolution().

Definition at line 2577 of file constraint_solver.h.

◆ objective

OptimizeVar* operations_research::Solver::SearchLogParameters::objective = nullptr

SearchMonitors will display values of objective or variables (both cannot be used together).

Definition at line 2564 of file constraint_solver.h.

◆ offsets

std::vector<double> operations_research::Solver::SearchLogParameters::offsets

Definition at line 2570 of file constraint_solver.h.

◆ scaling_factors

std::vector<double> operations_research::Solver::SearchLogParameters::scaling_factors

When displayed, objective or var values will be scaled and offset by the given values in the following way: scaling_factor * (value + offset).

Definition at line 2569 of file constraint_solver.h.

◆ variables

std::vector<IntVar*> operations_research::Solver::SearchLogParameters::variables

Definition at line 2565 of file constraint_solver.h.
