an arbitrary sequence satisfying the conditions: (i) 0 £ct£ 1, (ii) ct® 0, (iii) Stct ® ¥ ; e.g., ct = (1/t)¥, 0 < ¥ < 1.
(The sequence is included primarily for its effects when genetic plans are used as algorithms for artificial systems; it is used to drive the mutation rate to zero, while assuring that every allele is tried in all possible contexts. is not intended to have a natural system counterpart and its effects can be ignored in that context. See below.)
Algorithms in the subclass of just described will be designated . The performances observed at step 2.3 will be taken to be trials of a random variable in all that follows. Thus µE assigns a random variable
