4.1.1 Solution Representation and Generation     continued...

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.
