◆ AUTOMATIC

com.google.ortools.constraintsolver.LocalSearchMetaheuristic.Value.AUTOMATIC =(6) 
Lets the solver select the metaheuristic.

AUTOMATIC = 6;

◆ GENERIC_TABU_SEARCH

com.google.ortools.constraintsolver.LocalSearchMetaheuristic.Value.GENERIC_TABU_SEARCH =(5) 
Uses tabu search on a list of variables to escape local minima. The list
of variables to use must be provided via the SetTabuVarsCallback
callback.

final int com.google.ortools.constraintsolver.LocalSearchMetaheuristic.Value.GENERIC_TABU_SEARCH_VALUE = 5
static 
Uses tabu search on a list of variables to escape local minima. The list
of variables to use must be provided via the SetTabuVarsCallback
callback.

GENERIC_TABU_SEARCH = 5;

Definition at line 184 of file LocalSearchMetaheuristic.java.

◆ GREEDY_DESCENT

com.google.ortools.constraintsolver.LocalSearchMetaheuristic.Value.GREEDY_DESCENT =(1) 
Accepts improving (cost-reducing) local search neighbors until a local
minimum is reached.

GREEDY_DESCENT = 1;

Definition at line 78 of file LocalSearchMetaheuristic.java.

◆ GREEDY_DESCENT_VALUE

final int com.google.ortools.constraintsolver.LocalSearchMetaheuristic.Value.GREEDY_DESCENT_VALUE = 1

Definition at line 146 of file LocalSearchMetaheuristic.java.

◆ GUIDED_LOCAL_SEARCH

com.google.ortools.constraintsolver.LocalSearchMetaheuristic.Value.GUIDED_LOCAL_SEARCH =(2) 
Uses guided local search to escape local minima
(cf. http://en.wikipedia.org/wiki/Guided_Local_Search); this is generally
the most efficient metaheuristic for vehicle routing.

GUIDED_LOCAL_SEARCH = 2;

Definition at line 88 of file LocalSearchMetaheuristic.java.

◆ GUIDED_LOCAL_SEARCH_VALUE

final int com.google.ortools.constraintsolver.LocalSearchMetaheuristic.Value.GUIDED_LOCAL_SEARCH_VALUE = 2

◆ SIMULATED_ANNEALING

com.google.ortools.constraintsolver.LocalSearchMetaheuristic.Value.SIMULATED_ANNEALING =(3) 
Uses simulated annealing to escape local minima
(cf. http://en.wikipedia.org/wiki/Simulated_annealing).

SIMULATED_ANNEALING = 3;

◆ TABU_SEARCH_VALUE

final int com.google.ortools.constraintsolver.LocalSearchMetaheuristic.Value.TABU_SEARCH_VALUE = 4
static 
Uses tabu search to escape local minima
(cf. http://en.wikipedia.org/wiki/Tabu_search).

TABU_SEARCH = 4;

Definition at line 117 of file LocalSearchMetaheuristic.java.

◆ UNSET

com.google.ortools.constraintsolver.LocalSearchMetaheuristic.Value.UNSET =(0)

AUTOMATIC. But this value won't override others upon a proto MergeFrom(),
whereas "AUTOMATIC" will.

UNSET = 0;
