neigh_func_csa — The classical neighborhood relationship for the simulated annealing
x_neigh = neigh_func_csa(x_current,T,param)
the point for which we want to compute a neighbor
the current temperature
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.
