accept_func_default

The default Simulated Annealing acceptation function.

Calling Sequence

Level = accept_func_default(F_current, F_neigh, T)

Arguments

F_current

the current function value

F_neigh

the function value of the neighbour

T

the current temperature

Level

the level of acceptation, in the interval [0,1].

Description

The accept_func_default provides the default Simulated Annealing acceptation function.

If the level computed by the acceptation function is higher than the generated uniform random number in the interval [0,1], then the neighbour is accepted.

The formula used in the implementation is the following.

Level = exp(-(F_neigh - F_current)/max(T,%eps));
