NFL theorems prove evolutionary algorithms don't beat blind search (Talk.Origins)
From CreationWiki, the encyclopedia of creation science
- The No Free Lunch (NFL) theorems [Wolpert and Macready 1997] prove that evolutionary algorithms, when averaged across fitness functions, cannot outperform blind search. This means that an evolutionary algorithm can find a specified target only if complex specified information already resides in the fitness function. Evolutionary algorithms cannot account for the complex specified information we see in life; that information has to come from design.
