Class CoolingScheduleHyperbolic

java.lang.Object

org.opt4j.optimizer.sa.CoolingScheduleHyperbolic

All Implemented Interfaces:

CoolingSchedule

public class CoolingScheduleHyperbolic
extends Object
implements CoolingSchedule

The CoolingScheduleHyperbolic is a CoolingSchedule for the SimulatedAnnealing.

tn - final temperature
t0 - initial temperature
i - current iteration
n - maximal number of iterations
a - alpha value

The current temperature is calculated by t0 * (tn / t0)^(i/n).
