The average fitness for the GA was shown to be consistently better than the random search and the HC search, while the HC technique was, for the most part, significantly better than the random search.
Mutation accumulation was followed for 8000 generations and the resulting average fitness for the population calculated.
We have discussed the changes in the average fitness for an infinite asexual population under mutation and selection.
Our results show that the average population fitness and average fitness for the fittest organisms are higher in TS compared to FPS.
The blue and cyan lines show the average fitness for all chromosomes and for those that have not reached a goal, respectively.
In this case, frequency dependent selection tends to decrease the average fitness: for θ < 2 − 1 2, it is more likely that the average fitness of the population is decreased by a single random frequency dependent mutation; for θ > 2 − 1 2, it is more likely that it is increased.

The error threshold shows a phase transition for collective order parameters such the consensus sequence [ 11, 16], but not, for example, for the average fitness of the population, whose value does not greatly vary at the error threshold, although its dependence on mutation rate does [ 13].
If the population size is "n" then the fitness of ith chromosome is expressed as F i, and the average fitness of the population for ith generation is generally calculated using the following formula F_{text{avg}} sumlimits_{{i{ = 1}}}^{n} {F_{i} } (4).
Here, we study the correlation between recurrence time and average fitness of the relapse tumor for varying levels of preexisting resistance and find that the behavior is consistent with results of our earlier analysis.
Average frontier fitness (AFF) Average fitness of solutions in first frontier for each objective.
Thus populations can compete for the greatest average fitness of their members; those that have the greatest proportion of the relevant alleles, resulting in the greatest number of altruists being formed (emerging by chance), will win in this competition.
