Reliable Communication Network Design with EvolutionaryAlgorithms

Reichelt, Dirk; Rothlauf, Franz - Betriebswirtschaftliches Institut <Mannheim>; … - 2004

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...

Rothlauf, Franz; Gerstacker, Jürgen; Heinzl, Armin - 2003

This paper presents an investigation into the properties of the optimal communication spanningtree (OCST) problem. The OCST problem nds a spanning tree that connects all nodesand satises their communication requirements for a minimum total cost. The paper comparesthe properties of randomly...

Prüfer Numbers: A Poor Presentation of Spanning Trees for Evolutionary Search

Gottlieb, Jens; Julstrom, Bryant A.; Raidl, Günther; … - Universität <Mainz> / Lehrstuhl für … - 2000

The most important element in the design of a decoder-based evolutionary algorithmis its genotypic representation. The genotype-decoder pair must exhibit efficiency, locality, and heritability to enable effective evolutionary search.[...]

This report provides a spatial representation of hospital geography in Iowa and of the decisions of patients to … patronize hospitals. It begins with a brief analysis of hospital proximity and hospital proximity’s relationship to population … distributions and existing hospital capacity. This is followed with a discussion of hospital capacity as a proxy for the supply of …

Classification of Human Decision Behavior: Finding ModularDecision Rules with Genetic Algorithms

Rothlauf, Franz; Schunk, Daniel; Pfeiffer, Jella - Universität <Mainz> / Lehrstuhl für … - 2005

The understanding of human behavior in sequential decision tasks is im-portant for economics and socio-psychological sciences. In search tasks,for example when individuals search for the best price of a product, theyare confronted in sequential steps with different situations and they haveto...

Population Sizing for the RedundantTrivial Voting Mapping

Rothlauf, Franz - Betriebswirtschaftliches Institut <Mannheim>; … - 2003

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...
