Quote | Ewert, Dembski & Marks: Even moderately sized search problems require external assistance to be successful. The contribution of the external source to the search can be measured as active information. Sources of active information include (a) an oracle that provides fitness information (or scores) for the search, ...
| As has been pointed out many times before, the oracle represents the abstracted environment, and is the whole point of many evolutionary algorithms.
Quote | Ewert, Dembski & Marks: Since every constructive choice of priors has a corresponding deleterious choice, the average performance over all searches is the same as a random search [3], [4], [5], [8], [15], [19], [20], [21], [22], [23], [27], [28], [29], [30]. This search property is dubbed conservation of information [4], [5], [7], [9], [23] as popularized by the no free lunch theorem [3], [8], [15], [30]. |
This is highly misleading with respect to evolution. Adding zillions of footnotes doesn't resolve the ambiguity. We're not concerned with a highly chaotic search space, but one that is highly ordered. Nor are we discussing an arbitrary algorithm, but one adept at climbing fitness gradients.
