Coevolutionary minimal substrates are simple and abstract models that allow studying the relationships and codynamics between objective and subjective fitness.

Coevolutionary intransitivity in games: A landscape analysis

no code implementations16 Jan 2015 Hendrik Richter

Intransitivity is supposed to be a main reason for deficits in coevolutionary progress and inheritable superiority.

Analyzing coevolutionary games with dynamic fitness landscapes

no code implementations21 Mar 2016 Hendrik Richter

Coevolutionary games cast players that may change their strategies as well as their networks of interaction.

Dynamic landscape models of coevolutionary games

no code implementations28 Nov 2016 Hendrik Richter

In addition, fixation properties of the games and quantifiers characterizing the interaction networks are calculated numerically.

Scale-invariance of ruggedness measures in fractal fitness landscapes

no code implementations21 Dec 2016 Hendrik Richter

The paper deals with using chaos to direct trajectories to targets and analyzes ruggedness and fractality of the resulting fitness landscapes.

Visual art inspired by the collective feeding behavior of sand-bubbler crabs

no code implementations1 Sep 2017 Hendrik Richter

Sand--bubblers are crabs of the genera Dotilla and Scopimera which are known to produce remarkable patterns and structures at tropical beaches.

Information content of coevolutionary game landscapes

no code implementations20 Mar 2018 Hendrik Richter

Coevolutionary game dynamics is the result of players that may change their strategies and their network of interaction.

Properties of interaction networks, structure coefficients, and benefit-to-cost ratios

no code implementations29 May 2018 Hendrik Richter

Moreover, the coefficients are specific for a given interaction network modeled as regular graph, which is why we may call them specific structure coefficients.

Fixation properties of multiple cooperator configurations on regular graphs

no code implementations16 Nov 2018 Hendrik Richter

For interaction networks modeled as regular graphs and for weak selection, the emergence of cooperation can be assessed by structure coefficients, which are specific for a configuration and a graph.

Relationships between dilemma strength and fixation properties in coevolutionary games

no code implementations11 Jan 2019 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 modeled as a regular graph.

We study creating and analyzing symmetry and broken symmetry in digital art.

Evolution of Cooperation for Multiple Mutant Configurations on All Regular Graphs with $N \leq 14$ players

no code implementations9 Nov 2019 Hendrik Richter

Using structure coefficients defined for configurations describing such arrangements of any number of mutants, we provide results for weak selection to favor cooperation over defection on any regular graph with $N \leq 14$ vertices.

Convergence analysis of particle swarm optimization using stochastic Lyapunov functions and quantifier elimination

1 code implementation5 Feb 2020 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 quantifier elimination.

A color symmetry permutes the coloring of the objects consistently with their symmetry group.

Wrong Colored Vermeer: Color-Symmetric Image Distortion

no code implementations29 Jun 2021 Hendrik Richter

Color symmetry implies that the colors of geometrical objects are assigned according to their symmetry properties.

Spectral dynamics of guided edge removals and identifying transient amplifiers for death-Birth updating

no code implementations27 Apr 2022 Hendrik Richter

Also, the spectral dynamics possesses characteristic features useful for deducing links between structural and spectral properties and for distinguishing transient amplifiers among evolutionary graphs in general.
