Parallel Contextual Array Insertion Deletion P Systems and Pure 2D Eilenberg P Systems

Parallel contextual array insertion deletion P system (PCAIDPS) generating 2D rectangular picture languages, introduced in 2017, has more generating capacity than the other picture language generating devices like tiling systems and context-sensitive matrix grammars etc. In 2024 another interesting device called pure 2D Eilenberg P system (P2DEPS) based on pure 2D context-free grammars has been studied. In this paper, we compare the generative powers of these two P systems PCAIDPS and P2DEPS.
