# temp_law_default

A SA function which computed the temperature of the next temperature stage

## Calling Sequence

    T_next = temp_law_default(T,step_mean,step_var,temp_stage,n,param)

## Arguments

T

  the temperature applied during the last temperature stage

step_mean

  the mean of the objective function values computed during the last temperature stage

step_var

  the variance of the obejective function values computed during the last temperature stage

temp_stage

  the index of the current temperature stage

n

  the dimension of the decision variable (the x in f(x))

param

  a float between 0 and 1. Corresponds to the decrease in temperature of the geometric law (0.9 by default)

T_next

  the new temperature to be applied for the next temperature stage

## Description

- A SA function which computed the temperature of the next temperature stage

## Examples

    // This function implements the simple geometric temperature law
    function T = temp_law_default(T, step_mean, step_var)
      _alpha = 0.9;
      T = _alpha*T;
    endfunction
