چکیده

We present an application of Grammatical Evolution to the exploration of Lindenmayer systems. The resulting L-systems are expressed in the Postscript language, and as such a Postscript grammar was provided as input to the Grammatical Evolution algorithm. The system takes the form of an interactive evolutionary algorithm, with a human-in-theloop acting as the fitness function for the generated L-systems. The motivation for this research was to evolve a logo for the UCD Natural Computing Research & Applications group, and to this end the study was a success.

Global Distributed Evolution of L-Systems Fractals

Internet based parallel genetic programming (GP) creates fractal patterns like Koch’s snow flake. Pfeiffer, http://www.cs.ucl.ac.uk /staff/W.Langdon/pfeiffer.html, by analogy with seed/embryo development, uses Lindenmayer grammars and LOGO style turtle graphics written in Javascript and Perl. 298 novel pictures were produced. Images are placed in animated snow globes (computerised snowstorms) b...

Grammatical evolution to design fractal curves with a given dimension

Lindenmayer Grammars have been applied frequently to represent fractal curves. In this work, the ideas behind Grammar Evolution are used to automatically generate and evolve Lindenmayer Grammars that represent fractal curves with a fractal dimension that approximates a pre-defined required value. For many dimensions, this is a non trivial task to be performed manually. The procedure we are prop...

Evolving L-Systems to Capture Protein Structure Native Conformations

A protein is a linear chain of amino acids that folds into a unique functional structure, called its native state. In this state, proteins show repeated substructures like alpha helices and beta sheets. This suggests that native structures may be captured by the formalism known as Lindenmayer systems (L-systems). In this paper an evolutionary approach is used as the inference procedure for fold...

Feedback Control in the Evolution of Generative Lindenmayer Systems

This paper discusses the incorporation of feedback and feedback control in the modeling of biological and robotic systems via Lindenmayer representations. Context-free, context-sensitive, parametric, context-sensitive parametric and context-sensitive parametric Lindenmayer systems under feedback control are discussed. Proposals are made on how to modify generative context-sensitive parametric L...

Creation of a PostScript Type 1 logo font with MetaType 1

MetaType 1 is a tool created by Bogusław Jackowski, Janusz Nowacki, and Piotr Strzelczyk for creating PostScript Type 1 fonts. It uses METAPOST, t1utils and some AWK scripts to start from a METAPOST source with some special macros, resulting in the AFM, TFM and PFB files needed to use the font as any other PostScript font. MetaType 1 was used to create the Latin Modern fonts, derived from Compu...
