A variant of Tile Pasting P system for tiling patterns

摘要

Pasting Systems, Tile Pasting P Systems and their variants are syntactic methods to generate tiling patterns and tessellation using simple rules of gluing tiles at their edges. In this paper new models namely, tissue-like, evolution-conditional communication tile pasting P system (t-ECCTPPS) and Parametric Tile Pasting P Systems (PTPPS) and its variant tissue-like Parametric Tile Pasting P Systems(t-PTTTS) incorporating geometric transformation operations are introduced. The PTPPS and its variant are found to generate non-periodic tiling patterns. Comparison of these models with earlier models has also been discussed.
