of variables to use must be provided via the SetTabuVarsCallback
callback.

Definition at line 197 of file LocalSearchMetaheuristic.java.

◆ GREEDY_DESCENT

com.google.ortools.constraintsolver.LocalSearchMetaheuristic.Value.GREEDY_DESCENT =(1)

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 92 of file LocalSearchMetaheuristic.java.

◆ GUIDED_LOCAL_SEARCH_VALUE

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

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;

Definition at line 121 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;
