Do Random and Chaotic Sequences Really Cause Different PSO Performance?
Paul Moritz Nörenberg, Hendrik Richter
Our topic is performance differences between using random and chaos for particle swarm optimization (PSO). We take random sequences with different probability distributions and com…
Spectral dynamics of guided edge removals and identifying transient amplifiers for death-Birth updating
Hendrik Richter
The paper deals with two interrelated topics, identifying transient amplifiers in an iterative process and analyzing the process by its spectral dynamics, which is the change in th…
Wrong Colored Vermeer: Color-Symmetric Image Distortion
Hendrik Richter
Color symmetry implies that the colors of geometrical objects are assigned according to their symmetry properties. It is defined by associating the elements of the symmetry group w…
Designing color symmetry in stigmergic art
Hendrik Richter
Color symmetry is an extension of symmetry imposed by isometric transformations and means that the colors of geometrical objects are assigned according to the symmetry properties o…
Constructing transient amplifiers for death-Birth updating: A case study of cubic and quartic regular graphs
Hendrik Richter
A central question of evolutionary dynamics on graphs is whether or not a mutation introduced in a population of residents survives and eventually even spreads to the whole populat…
Convergence analysis of particle swarm optimization using stochastic Lyapunov functions and quantifier elimination
Maximilian Gerwien, Rick Voßwinkel, Hendrik Richter
This paper adds to the discussion about theoretical aspects of particle swarm stability by proposing to employ stochastic Lyapunov functions and to determine the convergence set by…
Evolution of Cooperation for Multiple Mutant Configurations on All Regular Graphs with players
Hendrik Richter
We study the emergence of cooperation in structured populations with any arrangement of cooperators and defectors on the evolutionary graph. Using structure coefficients defined fo…
Analyzing symmetry and symmetry breaking by computational aesthetic measures
Hendrik Richter
We study creating and analyzing symmetry and broken symmetry in digital art. Our focus is not so much on computer-generating artistic images, but rather on analyzing concepts and t…
Relationships between dilemma strength and fixation properties in coevolutionary games
Hendrik Richter
Whether or not cooperation is favored over defection in evolutionary games can be assigned by structure coefficients for any arrangement of cooperators and defectors on any network…
Fixation properties of multiple cooperator configurations on regular graphs
Hendrik Richter
Whether or not cooperation is favored in evolutionary games on graphs depends on the population structure and spatial properties of the interaction network. Population structures c…
Properties of interaction networks, structure coefficients, and benefit-to-cost ratios
Hendrik Richter
In structured populations the spatial arrangement of cooperators and defectors on the interaction graph together with the structure of the graph itself determines the game dynamics…
Information content of coevolutionary game landscapes
Hendrik Richter
Coevolutionary game dynamics is the result of players that may change their strategies and their network of interaction. For such games, and based on interpreting strategies as con…
Automatic Generation of Bounds for Polynomial Systems with Application to the Lorenz System
Klaus Röbenack, Rick Voßwinkel, Hendrik Richter
This study covers an analytical approach to calculate positively invariant sets of dynamical systems. Using Lyapunov techniques and quantifier elimination methods, an automatic pro…
Visual art inspired by the collective feeding behavior of sand-bubbler crabs
Hendrik Richter
Sand--bubblers are crabs of the genera Dotilla and Scopimera which are known to produce remarkable patterns and structures at tropical beaches. From these pattern-making abilities,…
Scale-invariance of ruggedness measures in fractal fitness landscapes
Hendrik Richter
The paper deals with using chaos to direct trajectories to targets and analyzes ruggedness and fractality of the resulting fitness landscapes. The targeting problem is formulated a…
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…
Analyzing coevolutionary games with dynamic fitness landscapes
Hendrik Richter
Coevolutionary games cast players that may change their strategies as well as their networks of interaction. In this paper a framework is introduced for describing coevolutionary g…
Coevolutionary intransitivity in games: A landscape analysis
Hendrik Richter
Intransitivity is supposed to be a main reason for deficits in coevolutionary progress and inheritable superiority. Besides, coevolutionary dynamics is characterized by interaction…
Codynamic Fitness Landscapes of Coevolutionary Minimal Substrates
Hendrik Richter
Coevolutionary minimal substrates are simple and abstract models that allow studying the relationships and codynamics between objective and subjective fitness. Using these models a…
