Current Problems in Computational Biology: A Study of P-Systems at The University of Sheffield

This study explores current issues in computational biology focusing on P-systems at The University of Sheffield, covering fundamentals, languages of recombinant DNA, membrane computing, basic definitions, variants, tissue/population P-systems, and more. The analysis includes descriptional complexity, model checking, structural operational semantics, and various case studies, concluding with the need for coherent semantics, a specification language, and tools.

  15. Other problems • descriptional complexity (comes with computational power) • model checking (CTL); attempts to model in Maude, Spin and Prism • structural operational semantics and Petri Nets • P systems as dynamic systems • model various case studies Verification and Testing & Computational Biology, Department of Computer Science, The University of Sheffield

  16. Conclusions • P systems are a non-standard computation mechanism inspired by cellular biology • A well developed theoretical approach (computational power, complexity) and some modelling approaches (v early stage) • What next: • Developing a coherent semantics • Defining a specification language • Tools Verification and Testing & Computational Biology, Department of Computer Science, The University of Sheffield
