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.
