The title, Enjoying Natural Computing,reflects one of the guiding principles of Mario’s functioning (in both his professional and his personal life): once you choose to do something, enjoy doing it. As a matter of fact, Mario is really successful in widely propagating this principle, e.g., it is very visible in the functioning of his Seville group. His contagious research enthusiasm, witnessed and enjoyed by his many sci- entific collaborators, must also be driven by this principle. A dominating feature of his character is his genuine altruism, a real devotion to the functioning of his friends and colleagues – this empathy for others is inexhaustible. His group tries to follow the “warning” which says: do not let Mario know that you need something, as then Mario is ready to drop everything and concentrate just on your problems. His scientific credentials are impressive, as: 1. his research interests are wide, ranging from very theoretical problems from com- putational complexity theory to very applied problems and tasks, such as, the design of a programming language that facilitates in silico experiments in membrane computing, 2. he initiated a number of novel research directions as well as solving several very technically challenging problems. In addition, Mario created “from scratch” an impressive research group in natural computing at the University of Seville. In fact, his group has become a sort of “pil- grimage venue” for researchers in membrane computing and other areas of natural computing. The “Brainstorming Week on Membrane Computing”, organized annually by him since 2004, has become a famous meeting forum for researchers from all over the world. One can safely say that a big part of research problems (and their solutions) in the very active area of membrane computing originated during these meetings. His achievements are well-recognized by the scientific community. A manifestation of this recognition was the overwhelming response to our invitations to contribute to this Festschrift. As a result, this volume contains contributions from researchers from 15 different countries. The contributions, which went through a thorough refereeing procedure, cover a wide spectrum of research areas, including membrane computing, spiking neural networks, phylogenetic networks, ant colonies optimization, workbench for biocomputing, reaction systems, entropy of computation, rewriting systems, and insertion-deletion systems. In this way, the volume reflects well the broad range of research interests of Mario. VIII Foreword Dear Mario: Thank you for your collaboration and friendship. We wish you continuous success and satisfaction in science in the years to come.

  • The EATCS Award 2020 Laudatio for Toniann (Toni)Pitassi
    The EATCS Award 2020 Laudatio for Toniann (Toni)Pitassi The EATCS Award 2021 is awarded to Toniann (Toni) Pitassi University of Toronto, as the recipient of the 2021 EATCS Award for her fun- damental and wide-ranging contributions to computational complexity, which in- cludes proving long-standing open problems, introducing new fundamental mod- els, developing novel techniques and establishing new connections between dif- ferent areas. Her work is very broad and has relevance in computational learning and optimisation, verification and SAT-solving, circuit complexity and communi- cation complexity, and their applications. The first notable contribution by Toni Pitassi was to develop lifting theorems: a way to transfer lower bounds from the (much simpler) decision tree model for any function f, to a lower bound, the much harder communication complexity model, for a simply related (2-party) function f’. This has completely transformed our state of knowledge regarding two fundamental computational models, query algorithms (decision trees) and communication complexity, as well as their rela- tionship and applicability to other areas of theoretical computer science. These powerful and flexible techniques resolved numerous open problems (e.g., the su- per quadratic gap between probabilistic and quantum communication complex- ity), many of which were central challenges for decades. Toni Pitassi has also had a remarkable impact in proof complexity. She in- troduced the fundamental algebraic Nullstellensatz and Ideal proof systems, and the geometric Stabbing Planes system. She gave the first nontrivial lower bounds on such long-standing problems as weak pigeon-hole principle and models like constant-depth Frege proof systems. She has developed new proof techniques for virtually all proof systems, and new SAT algorithms.

  • Concurrency Theory: a Historical Perspective on Coinduction and Process Calculi
    CONCURRENCY THEORY: A HISTORICAL PERSPECTIVE ON COINDUCTION AND PROCESS CALCULI Jos Baeten, Davide Sangiorgi Readers:Luca Aceto and Robert van Glabbeek 1 INTRODUCTION Computer science is a very young science, that has its origins in the middle of the twentieth century. For this reason, describing its history, or the history of an area of research in computer science, is an activity that receives scant attention. The discipline of computer science does not have a clear demarcation, and even its name is a source of debate. Computer science is sometimes called informatics or information science or information and communication science. A quote widely attributed to Edsger Dijkstra is Computer science is no more about computers than astronomy is about telescopes. If computer science is not about computers, what is it about? We claim it is about behavior. This behavior can be exhibited by a computer executing a program, but equally well by a human being performing a series of actions. In general, behavior can be shown by any agent. Here, an agent is simply an entity that can act. So, computer science is about behavior, about processes, about things happening over time. We are concerned with agents that are executing actions, taking input, emitting output, communicating with other agents. Thus, an agent has behavior, e.g., the execution of a software system, the actions of a machine or even the actions of a human being. Behavior is the total of events or actions that an agent can perform, the order in which they can be executed and maybe other aspects of this execution such as timing, probabilities or evolution.

  • Derick Wood in Memoriam
    Derick Wood In Memoriam My dear friend and colleague Derick Wood passed away in Waterloo, On- tario, on October 4, after a long and devastating illness. Apart from the loving wife Mary and other family, he will be missed by the theoretical computer sci- ence community all over the world. The respect and appreciation towards Derick’s scientific work became re- cently apparent in the special issue of The Journal of Universal Computer Sci- ence, published on the occasion of Derick’s 70th birthday. The issue appeared also as a book with many pictures. I am sure that the numerous contributors to this issue, as well as other friends and colleagues of Derick, have their own par- ticular memories of this extraordinary person and outstanding scientist. This writing reflects mainly my personal recollections. Derick Wood was born in Lancashire, England, in 1940. He received his BSc and PhD degrees from the University of Leeds, England, in 1963 and 1968, respectively. He was a Postdoctoral Fellow at the Courant Institute, New York University, from 1968 to 1970. This is where I first met Derick, in an Italian restaurant in lower Manhattan in June 1970. We discussed mostly problems concerning context-free parsing but I remember Derick also eagerly awaiting phone calls from McMaster University in Hamilton, Ontario. Very soon after that he joined the Unit of Computer Science at McMaster University, being the Chair of Computer Science from 1979 to 1982. As will be explained below in connection with our MSW work, I stayed numerous times in Derick’s house on Bond Street, enjoying his hospitality.

  • Novel Frameworks for Mining Heterogeneous and Dynamic
    Novel Frameworks for Mining Heterogeneous and Dynamic Networks A dissertation submitted to the Graduate School of the University of Cincinnati in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Electrical and Computer Engineering and Computer Science of the College of Engineering by Chunsheng Fang B.E., Electrical Engineering & Information Science, June 2006 University of Science & Technology of China, Hefei, P.R.China Advisor and Committee Chair: Prof. Anca L. Ralescu November 3, 2011 Abstract Graphs serve as an important tool for discrete data representation. Recently, graph representations have made possible very powerful machine learning algorithms, such as manifold learning, kernel methods, semi-supervised learning. With the advent of large-scale real world networks, such as biological networks (disease network, drug target network, etc.), social networks (DBLP Co- authorship network, Facebook friendship, etc.), machine learning and data mining algorithms have found new application areas and have contributed to advance our understanding of proper- ties, and phenomena governing real world networks. When dealing with real world data represented as networks, two problems arise quite naturally: I) How to integrate and align the knowledge encoded in multiple and heterogeneous networks? For instance, how to find out the similar genes in co-disease and protein-protein inter- action networks? II) How to model and predict the evolution of a dynamic network? A real world exam- ple is, given N years snapshots of an evolving social network, how to build a model that can cap- ture the temporal evolution and make reliable prediction? In this dissertation, we present an innovative graph embedding framework, which identifies the key components of modeling the evolution in time of a dynamic graph.

I am fully aware that I can touch only a few facts of his amazing scientific career. Rather than trying to give a complete picture of a highly recognized academy professor, I hope to uncover a few glimpses of the life of a warm and beloved scientist, Arto as he is known by his students and colleagues, or A ija as he is known by his grandchildren. Arto was born in Turku on the sixth of June 1934 to an academic family. His father was a professor of philosophy at Turku University, which became the home university of Arto as well. His son Kai continues the traditions of the family at another home university of Arto in Canada. After graduating in 1954 at Turku University Arto went to Berkeley for graduate studies. He returned to his home town, defended his Ph.D. in 1960, and was appointed professor of mathematics at Turku University in 1966, a position he held for more than 30 years. Approximately half of that time, however, he was an academy professor the most prestigious scientific position in Finland. Turku has always been the home of Arto both scientifically and personally. This, however, has not prevented him from creating several secondary homes abroad.
