Information flow and Laplacian dynamics on local optima networks
Hendrik Richter, Sarah L. Thomson
We propose a new way of looking at local optima networks (LONs). LONs represent fitness landscapes; the nodes are local optima, and the edges are search transitions between them. M…
Do Random and Chaotic Sequences Really Cause Different PSO Performance? Further Results
{Paul Moritz Nörenberg, Hendrik Richter
Empirical results show that PSO performance may be different if using either chaotic or random sequences to drive the algorithm's search dynamics. We analyze the phenomenon by eval…
Model based MIN/MAX override control of centrifugal compressor systems
Rico Schulze, Hendrik Richter
We consider an application-oriented nonlinear control of centrifugal compressors. Industrial applications require the compressor system to adjust to variable process demands and to…
Dynamic landscape models of coevolutionary games
Hendrik Richter
Players of coevolutionary games may update not only their strategies but also their networks of interaction. Based on interpreting the payoff of players as fitness, dynamic landsca…
