Interface TemperatureFunction

All Known Implementing Classes:

BoltzTemperatureFunction, ExpTemperatureFunction, FastTemperatureFunction, GSATemperatureFunction, SimpleTemperatureFunction

public interface TemperatureFunction

A temperature function defines a temperature schedule used in simulated annealing. In general, the temperature for the visiting distribution (proposal generation) may not be equal to the temperature for determining the acceptance probability.

Method Detail

visitingTemperature

double visitingTemperature(int t)

Gets the visiting temperature \(T^V_t\) at time t.

Parameters:

t - the time at which to get a temperature, or the annealing parameter, same as the iteration number until reannealing

Returns:

the visiting temperature at time t

acceptanceTemperature

double acceptanceTemperature(int t)

Gets the acceptance temperature \(T^A_t\) at time t.

Parameters:

t - the time at which to get a temperature, or the annealing parameter, same as the iteration number until reannealing

Returns:

the acceptance temperature at time t
