according to the application and the preference of the researcher. Values
of between 0.001 and 0.01 are not unusual for the mutation probability.
This means that the bit at each site on the bitstring is flipped, on average,
between 0.1 and 1.0 percent of the time. One fixed value is used for each
generation and often is maintained for an entire run.
Since there are 64 bits in the example problem’s population (8 bits ×
8 individuals), it is quite possible that none would be altered as a result
of mutation, so we will consider the population of Figure 4.4(b) as
the “final” population after one iteration of the GA procedure. Going
through the entire GA procedure ...
