When using this strategy it is recommended that the probability of accepting an increase in f be changed from that given by equation (63) to:
where is the average step size, so that is a measure of the effectiveness of the change made. As the size of the step taken is considered in calculating does not need to be adjusted when T is changed.
For problems with integer control variables, the simple strategy whereby new trial solutions are generated according to the formula:
where is a vector of random integers in the range often suffices.
