## Name

neigh_func_csa — The classical neighborhood relationship for the simulated
annealing

## Calling Sequence

x_neigh = neigh_func_csa(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
