Query: Subpopulation Diversity Based Selecting Migration Moment in Distributed
  Evolutionary Algorithms   In distributed evolutionary algorithms, migration interval is used to decide
migration moments. Nevertheless, migration moments predetermined by intervals
cannot match the dynamic situation of evolution. In this paper, a scheme of
setting the success rate of migration based on subpopulation diversity at each
interval is proposed. With the scheme, migration still occurs at intervals, but
the probability of immigrants entering the target subpopulation will be
determined by the diversity of this subpopulation according to a proposed
formula. An analysis shows that the time consumption of our scheme is
acceptable. In our experiments, the basement of parallelism is an evolutionary
algorithm for the traveling salesman problem. Under different value
combinations of parameters for the formula, outcomes for eight benchmark
instances of the distributed evolutionary algorithm with the proposed scheme
are compared with those of a traditional one, respectively. Results show that
the distributed evolutionary algorithm based on our scheme has a significant
advantage on solutions especially for high difficulty instances. Moreover, it
can be seen that the algorithm with the scheme has the most outstanding
performance under three value combinations of above-mentioned parameters for
the formula.
