◆ base_objective

IntegerValue operations_research::sat::NeighborhoodGenerator::SolveData::base_objective = IntegerValue(0)

Definition at line 412 of file cp_model_lns.h.

◆ deterministic_limit

double operations_research::sat::NeighborhoodGenerator::SolveData::deterministic_limit = 0.0

The deterministic time limit given to the solver for this neighborhood.

Definition at line 397 of file cp_model_lns.h.

◆ deterministic_time

double operations_research::sat::NeighborhoodGenerator::SolveData::deterministic_time = 0.0

The time it took to solve this neighborhood.

Definition at line 400 of file cp_model_lns.h.

◆ difficulty

double operations_research::sat::NeighborhoodGenerator::SolveData::difficulty = 0.0

The difficulty when this neighborhood was generated.

Definition at line 394 of file cp_model_lns.h.

◆ initial_best_objective

IntegerValue operations_research::sat::NeighborhoodGenerator::SolveData::initial_best_objective = IntegerValue(0)

Objective information. These only refer to the "internal" objective without scaling or offset so we are exact and it is always in the minimization direction.

The initial best objective is the one of the best known solution at the time the neighborhood was generated.
The base objective is the one of the base solution from which this neighborhood was generated.
The new objective is the objective of the best solution found by solving the neighborhood.

Definition at line 411 of file cp_model_lns.h.

◆ new_objective

IntegerValue operations_research::sat::NeighborhoodGenerator::SolveData::new_objective = IntegerValue(0)

Definition at line 413 of file cp_model_lns.h.

◆ status

CpSolverStatus operations_research::sat::NeighborhoodGenerator::SolveData::status = CpSolverStatus::UNKNOWN

The status of the sub-solve.

Definition at line 391 of file cp_model_lns.h.

◆ task_id

int operations_research::sat::NeighborhoodGenerator::SolveData::task_id = 0

For debugging.
