Class SimulatedAnnealing

java.lang.Object

org.opt4j.core.optimizer.AbstractOptimizer

org.opt4j.optimizer.sa.SimulatedAnnealing

All Implemented Interfaces:

Optimizer

public class SimulatedAnnealing
extends AbstractOptimizer

The SimulatedAnnealing is a standard implementation of the optimization heuristic. This heuristic optimizes a single objective (multi-objective problems are optimized by the sum of all objectives).
