Evolving Distributed Algorithms With Genetic Programming

“…Although this approach is very simple, the results of our experiments were often significantly better with this convergence prevention method turned on than without it [293,228,305]. Additionally, in none of our experiments, the outcomes were influenced negatively by this filter, which makes it even more robust than other methods for convergence prevention like sharing or variety preserving.…”

“…Especially the latter approach, the simple convergence prevention algorithm (SCP ), has shown to be very beneficial in many different applications [293,228,305].…”

“…Which of the two approaches is better has not yet been tested with comparative experiments and is part of our future work not related to this thesis. At the present moment, we assume that in real-valued search or problem spaces, clearing should be more suitable whereas we know from experiments using our approach only that SCP performs very good in combinatorial problems [228,305]…”

“…Based on these fitness values, algorithms like Tournament selection or fitness proportionate approaches will pick elements in a way that preserves the pressure into the direction of the Pareto frontier but also leads to a balanced and sustainable variety in the population. The benefits of this approach have been shown, for instance, in [228,305].…”

Capacitated arc routing problem in uncertain environments

“…[9] gives a comprehensive survey of the aforementioned problems. [10] and [11] consider dynamic replanning for VRP in case of unforseen situations such as traffic jams.…”
