Unformatted text preview: introduce a better individual with a new property into. This prevents process of reproduction from degeneration. In genetic algorithms mutation plays usually secondary role. Mutation rate is usually assumed on the level much below 1%. In our example mutation is equivalent to the random bit change of a given pattern. In this simple example with short strings and small population with a typical mutation rate of 0.1%, our patterns remain practically unchanged by the mutation process. The second generation for our example is shown in 8 Table If size of the population from one generation to another is the same, therefore two parents should generate two children. By combining two strings two another...
