accept_func_vfsa

The Very Fast Simulated Annealing acceptation function.

Syntax

Level = accept_func_vfsa(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_vfsa provides the Very Fast 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 = 1 / (1 + exp(-(F_current - F_neigh)/max(T,%eps)));

Examples

level = accept_func_vfsa(10, 9, 10)
