Uses of Assignment in com.google.ortools.constraintsolver
Methods in com.google.ortools.constraintsolver that return AssignmentModifier and TypeMethodDescriptionRoutingModel.compactAndCheckAssignment(Assignment assignment) Same as CompactAssignment() but also checks the validity of the final
compact solution; if it is not valid, no attempts to repair it are made
(instead, the method returns nullptr).RoutingModel.compactAssignment(Assignment assignment) Converts the solution in the given assignment to routes for all vehicles.
If the returned vector is route_indices, route_indices[i][j] is the index
for jth location visited on route i.RoutingModel.FastSolveFromAssignmentWithParameters(Assignment assignment, RoutingSearchParameters search_parameters, boolean check_solution_in_cp) Improves a given assignment using unchecked local search.
If check_solution_in_cp is true the final solution will be checked with
the CP solver.
As of 11/2023, only works with greedy descent.RoutingModel.FastSolveFromAssignmentWithParameters(Assignment assignment, RoutingSearchParameters search_parameters, boolean check_solution_in_cp, SWIGTYPE_p_absl__flat_hash_setT_operations_research__IntVar_p_t touched) Improves a given assignment using unchecked local search.
If check_solution_in_cp is true the final solution will be checked with
the CP solver.
As of 11/2023, only works with greedy descent.RoutingModel.GetFirstSolutionHint()Returns the current hint assignment.Solver.GetOrCreateLocalSearchState()Returns (or creates) an assignment representing the state of local search.SolutionCollector.last_solution_or_null()Returns the last solution if there are any, nullptr otherwise.Solver.makeAssignment()This method creates an empty assignment.Solver.makeAssignment(Assignment a) This method creates an assignment which is a copy of 'a'.RoutingModel.mutablePreAssignment()RoutingModel.preAssignment()Returns an assignment used to fix some of the variables of the problem.
In practice, this assignment locks partial routes of the problem.RoutingModel.readAssignment(String file_name) Reads an assignment from a file and returns the current solution.
Returns nullptr if the file cannot be opened or if the assignment is not
valid.RoutingModel.readAssignmentFromRoutes(long[][] routes, boolean ignore_inactive_indices) Restores the routes as the current solution.RoutingModel.restoreAssignment(Assignment solution) Restores an assignment as a solution in the routing model and returns the
new solution.Solver.RunUncheckedLocalSearch(Assignment initial_solution, LocalSearchFilterManager filter_manager, LocalSearchOperator ls_operator, SearchMonitor[] monitors, RegularLimit limit) Experimental: runs a local search on the given initial solution, checking
the feasibility and the objective value of solutions using the filter
manager only (solutions are never restored in the CP world).Solver.RunUncheckedLocalSearch(Assignment initial_solution, LocalSearchFilterManager filter_manager, LocalSearchOperator ls_operator, SearchMonitor[] monitors, RegularLimit limit, SWIGTYPE_p_absl__flat_hash_setT_operations_research__IntVar_p_t touched) Experimental: runs a local search on the given initial solution, checking
the feasibility and the objective value of solutions using the filter
manager only (solutions are never restored in the CP world).SolutionCollector.solution(int n) Returns the nth solution.RoutingModel.solve()Solves the current routing model; closes the current model.
This is equivalent to calling
SolveWithParameters(DefaultRoutingSearchParameters())
or
SolveFromAssignmentWithParameters(assignment,
DefaultRoutingSearchParameters()).RoutingModel.solve(Assignment assignment) Solves the current routing model; closes the current model.
This is equivalent to calling
SolveWithParameters(DefaultRoutingSearchParameters())
or
SolveFromAssignmentWithParameters(assignment,
DefaultRoutingSearchParameters()).RoutingModel.SolveFromAssignmentsWithParameters(SWIGTYPE_p_std__vectorT_operations_research__Assignment_const_p_t assignments, RoutingSearchParameters search_parameters) Same as above but will try all assignments in order as first solutions

the initial solution.RoutingModel.SolveWithIteratedLocalSearch(RoutingSearchParameters search_parameters) Solves the current routing model by using an Iterated Local Search
approach.RoutingModel.solveWithParameters(RoutingSearchParameters search_parameters) Solves the current routing model with the given parameters.Methods in com.google.ortools.constraintsolver with parameters of type AssignmentModifier and TypeMethodDescriptionbooleanLocalSearchFilter.accept(Assignment delta, Assignment deltadelta, long objective_min, long objective_max) Accepts a "delta" given the assignment with which the filter has been
synchronized; the delta holds the variables which have been modified and
their new value.
If the filter represents a part of the global objective, its contribution
must be between objective_min and objective_max.
Sample: supposing one wants to maintain a[0,1] + b[0,1] <= 1,
for the assignment (a,1), (b,0), the delta (b,1) will be rejected
but the delta (a,0) will be accepted.
TODO(user): Remove arguments when there are no more need for those.booleanLocalSearchFilterManager.accept(LocalSearchMonitor monitor, Assignment delta, Assignment deltadelta, long objective_min, long objective_max) Returns true iff all filters return true, and the sum of their accepted
objectives is between objective_min and objective_max.
