This paper investigates GA approaches for solving the reliable communicationnetwork design problem. For solving this problem a graph withminimum cost must be found that satises a given network reliabilityconstraint. To consider the additional reliability constraint dierent approachesare...

For the reliable communication network design (RCND) problem links areunreliable and for each link several options are available with dierent reliabilitiesand costs. The goal is to nd a cost-minimal communicationnetwork design that satises a pre-dened overall reliability constraint.This paper...

In diesem Beitrag wird ein Simultanplanungsansatz für die Flugplanerstellung vorgestellt.Bisherige Ansätze zur Flugplanerstellung separieren das Problem und lassen deshalb Interdependenzenzwischen den Problemvariablen unberücksichtigt. In dem vorgestellten Planungsansatzwerden mittels eines...

This paper investigates how the use of the trivial voting (TV) mapping influences the performanceof genetic algorithms (GAs). The TV mapping is a redundant representation for binaryphenotypes. A population sizing model is presented that quantitatively predicts the influence ofthe TV mapping and...

An … investigation into the bias of the edge-set encoding showsthat the crossover operator of the edge-set encoding without heuristics … isunbiased, that means it does not favor particular types of trees. In contrast,the crossover operator with heuristics is biased …
