Summary: §6 The Maximal Speed of Adaptation

Summary: (1) A first estimate of how long a problem will take in the solving might be given by the product of the possibilities in its components, assuming independence.
(2) This is a bad estimator, being biassed. It is in fact an upper bound of the true value.
(3) By the use of models the process of search can often be hastened.
(4) Often the components are not independent, and only a portion of the product-space need be searched. Various factors (described) may have this effect.
(5) Selection by components may be possible. It reduces the time to its logarithm.
(6) There is a minimal time for the solution of a problem (or adaptation): it is the time that the fastest isomorphic system can get the answer out in binary notation. 4650, 4668
