Mutation was used in the simple flip-bit with probability 1/l,
where l is the length of chromosome, and in MWM which adds to
1/l the probability produced by the wave function, with final result
limited to the maximum of 1. The used roughness of the wave
function (Equation 1) is 1 and thinness is 3 (Figure 2).
Replacement was experimented in three forms, generational
where the best offspring replace all parents, tournament between
one parent and one offspring, and MDR. In this experiment we
use binary tournaments in the MDR operator.
