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.

Designing color symmetry in stigmergic art

no code implementations28 Jun 2021 Hendrik Richter

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

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.

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.

Analyzing symmetry and symmetry breaking by computational aesthetic measures

no code implementations15 Oct 2019 Hendrik Richter

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

Codynamic Fitness Landscapes of Coevolutionary Minimal Substrates

no code implementations23 Apr 2014 Hendrik Richter

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