Name

neigh_func_fsa — The Fast Simulated Annealing neghborhood relationship

Calling Sequence

x_neigh = neigh_func_fsa(x_current,T,param)

Parameters

x_current

the point for which we want to compute a neighbor

T

the current temperature

param

a vector with the same size than x_current. A normalisation vector which allows to distort the shape of the neighborhood. This parameter allows to take into account the differences of interval of variation between variables. By default, this parameter is set to a vector of ones.

x_neigh

the computed neighbor

Description

  • This function computes the FSA neighborhood of a given point. The corresponding distribution is a Cauchy distribution which is more and more peaked as the temperature decrease.
