neigh_func_csa

The classical neighborhood relationship for the simulated annealing

Calling Sequence

x_neigh = neigh_func_csa(x_current,T,param)

Arguments

: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 implements the classical neighborhood relationship for the simulated annealing. The neighbors distribution is a gaussian distribution which is more and more peaked as the temperature decrease.
