Part of the broader research field of natural computing, Membrane Computing is an area within computing science that aims to abstract computing ideas and models from the structure and functioning of living cells, as well as from the way the cells are organized in tissues or higher order structures. It studies models of computation (known as P systems) inspired by the biochemistry of cells, in particular by the role of membranes in the compartmentalization of living cells into "protected reactors".This handbook provides both a comprehensive survey of available knowledge and established research topics, and a guide to recent developments in the field, covering the subject from theory to applications. The handbook is suitable both for introducing novices to this area of research, and as a main source of reference for active researchers. It sets out the necessary biological and formal background, with the introductory chapter serving as a gentle introduction to and overview of membrane computing. Individual chapters, written by leading researchers in membrane computing, present the state of the art of all main research trends and include extensive bibliographies.

Marcus Contextual Grammars is the first monograph to present a class of grammars introduced about three decades ago, based on the fundamental linguistic phenomenon of strings-contexts interplay (selection). Most of the theoretical results obtained so far about the many variants of contextual grammars are presented with emphasis on classes of questions with relevance for applications in the study of natural language syntax: generative powers, descriptive and computational complexity, automata recognition, semilinearity, structure of the generated strings, ambiguity, regulated rewriting, etc. Constant comparison with families of languages in the Chomsky hierarchy is made. Connections with non-linguistic areas are established, such as molecular computing. Audience: Researchers and students in theoretical computer science (formal language theory and automata theory), computational linguistics, mathematical methods in linguistics, and linguists interested in formal models of syntax.

First Published in 1994. The central problem of the “classic†formal language theory concerns the generation (the recognition) of languages by grammars (automata, respectively). However, in present day computer science, in artificial intelligence, in cognitive psychology and in other related fields we have to deal more and more with complex tasks distributed among a set of “ processors†, which are working together in a well defined way. Parallel computers, computer nets, distributed data bases and knowledge sources are practical materializations of this idea. Similarly, the psychologists speak about the modularity of mind, in problem solving theories there appear many models based on cognitive agents’ cooperation. As the formal language theory is involved in most of these circumstances (for example, as a theoretical framework, well developed from a mathematical point of view, for modelling aspects whose essence can be captured at the level of symbol systems, of the syntax of collections of strings of abstract symbols), a clear challenge appears for it: to consider systems o f grammars/automata, working together for generating/recognizing a language. In this context, notions such as distribution, cooperation, communication, concurrency, synchronization, parallelism etc. should be formalized and enlightened. The present monograph is an attempt to answer this challenge.

The finite - infinite interplay is central in human thinking, from ancient philosophers and mathematicians (Zeno, Pythagoras), to modern mathe matics (Cantor, Hilbert) and computer science (Turing, Godel). Recent developments in mathematics and computer science suggest a) radically new answers to classical questions (e. g. , does infinity exist?, where does infinity come from?, how to reconcile the finiteness of the human brain with the infinity of ideas it produces?), b) new questions of debate (e. g. , what is the role played by randomness?, are computers capable of handling the infinity through unconventional media of computation?, how can one approximate efficiently the finite by the infinite and, conversely, the infinite by finite?). Distinguished authors from around the world, many of them architects of the mathematics and computer science for the new century, contribute to the volume. Papers are as varied as Professor Marcus'' activity, to whom this volume is dedicated. They range from real analysis to DNA com puting, from linguistics to logic, from combinatorics on words to symbolic dynamics, from automata theory to geography, and so on, plus an incursion into the old history of conceptions about infinity and a list of philosophical "open problems". They are mainly mathematical and theoretical computer science texts, but not all of them are purely mathematical.

This volume originated in the Workshop on Membrane Computing, WMC- CdeA 2002, which took place in Curtea de Arge, s, Romania, during August 19- 23, 2002.This was the third annual workshop held in Curtea de Arge,s.The ?rst one, Workshop on Multiset Processing, WMP-CdeA 2000, took place in August 2000, and the proceedings were published in Lecture Notes in Computer Science, volume 2235.The second one, Workshop on Membrane Comp- ing, WMC-CdeA 2001, took place in August 2001, and selected papers were published as a special issue of Fundamenta Informaticae, volume 49, numbers 1-3, 2002. The aim of these workshops is to provide a stimulating environment for - searchers working in the area covered by a given workshop, so that existing sci- ti?c collaborations can be strengthened, and new collaborations (and friendships) can be initiated.Indeed, all three workshops held up to now were of such ch- acter, with very international attendance and collaboration taking place across national and scienti?c boundaries.

Molecular computing is a rapidly growing subarea of natural computing. On the one hand, molecular computing is concerned with the use of bio-molecules for the purpose of actual computations while, on the other hand, it attempts to understand the computational nature of molecular processes going on in living cells.The book presents a unique and authorative state-of-the-art survey on current research in molecular computing: 30 papers by leading researchers in the area are drawn together on the occasion of the 70th birthday of Tom Head, a pioneer in molecular computing. Among the topics addressed are molecular tiling, DNA self-assembly, splicing systems, DNA-based cryptography, DNA word design, gene assembly, and membrane computing.

This Festschrift celebrates the 70th birthday of Arto Kustaa Salomaa (born in Turku, Finland on June 6, 1934), one of the most in?uential researchers in theoretical computer science. Most ofhis researchconcernstheory - he is one of the founding fathers of formal language and automata theory, but he has also made important contributions to cryptography and natural computing. His approach to research in theoretical computer science is exemplary and inspirational for his students, collaborators, andthereadersofhispapersandbooks. Forhim,theroleoftheory(incomputer science) is to discover general rules of information processing that hold within computer science and in the world around us. One should not waste time on research concerning passing artifacts (or fashionable topics of the moment) in computer science - theory should be permanently predictive, insightful, and inspiring. That's why we chose the title "Theory is Forever". The main source of his in?uence on theoretical computer science is his publi- tions. Arto is a born writer - his papers and books are always most elegant.He has a unique gift for identifying the real essence of a research problem, and then presenting it in an incisive and eloquent way. He can write about a very involved formal topic and yet avoid a (much too common) overformalization. Many of his writings are genuine jewels and belong to the classics of theoreticalcomputer science. Theyhaveinspiredgenerationsofstudentsandresearchers. Indeed,even computers as well as computer science have learned a lot from Arto's publi- tions - this is nicely illustrated by DADARA on the cover of this volume.

Membrane computing is a branch of natural computing which investigates computing models abstracted from the structure and functioning of living cells and from their interactions in tissues or higher-order biological structures. The models considered, called membrane systems (P systems), are parallel, distributed computing models, processing multisets of symbols in cell-like compartmental architectures. In many applications membrane systems have considerable advantages – among these are their inherently discrete nature, parallelism, transparency, scalability and nondeterminism.In dedicated chapters, leading experts explain most of the applications of membrane computing reported so far, in biology, computer science, computer graphics and linguistics. The book also contains detailed reviews of the software tools used to simulate P systems.

Seville, one of the most beautiful cities in Spain, is at its best in October. An explosion of colour and contrast: ?amenco, bull?ghting, and a lively at- sphere in the streets due to the open and friendly nature of its people. The river Guadalquivir, the Cathedral and the Golden Tower are all places full of magic where the visitor can feel the spirit of a city which is eternally romantic. The series of International Conferences Unconventional Computation (UC),https://www.cs.auckland.ac.nz/CDMTCS/conferences/uc/isdevoted to all aspects of unconventional computation, theory as well as experiments and applications. Typical, but not exclusive, topics are: natural computing including quantum, cellular,molecular, neural and evolutionarycomputing; chaosand - namical systems based computing; and various proposals for computations that go beyond the Turing model. The ?rst venue of the Unconventional Computation Conference (formerly called Unconventional Models of Computation) was Auckland, New Zealand in 1998; subsequent sites of the conference were Brussels, Belgium in 2000 and Kobe, Japan in 2002. The titles of the proceedings volumes from past UC Conferences are as follows: 1. C.S. Calude, J. Casti, M.J. Dinneen (eds.).
