We were very pleased to receive a record number of submissions this year covering the spectrum of combinatorics and its applications. The presentations will cover many exciting new results and build connections between research areas. We hope you will be able to attend all the lectures and the two poster sessions. We encourage you to ask questions, discuss the material during breaks and participate fully in the FPSAC experience.
Our thanks goes out to everyone attending FPSAC 2010, and especially the members of the Program and Organizing Committees. We also thank the following organizations for their financial support: the National Science Foundation, the National Security Agency, the San Francisco State University College of Science and Engineering and Department of Mathematics, the Fields Institute, Elsevier, and Lindo Systems. Finally, we hope everyone will join us in thanking Federico Ardila and Matthias Beck for taking on the huge job of co-chairing the Organizing Committee.

This Proceedings volume is devoted to the Aofa'10, 21st International Meeting on Probabilistic, Combinatorial, and Asymptotic Methods for the Analysis of Algorithms, which was held at the Vienna University of Technology, Austria, during June 28 - July 2, 2010. This conference is the first joint meeting of two previous conference and seminar series on ``Mathematics and Computer Science'' and ``Analysis of Algorithms''. The common aim of these and the present meeting is to study discrete objects that appear as data structures or algorithms (including graphs, networks etc.) by mathematical methods, in particular by probabilistic, combinatorial and asymptotic methods. However, the topics of the conference are meant in a broad sense and so the programme committee selected 41 papers covering a wide range of fields. The 41 papers were presented in 30 minutes talks and all of them appear in this DMTCS Proceedings volume.
The programme of the conference was complemented by the following five 60 minutes invited lectures:
Noga Alon (Tel Aviv University, Israel)Color Coding: Variations and Applications
Yuliy Baryshnikov (Bell Laboratories, USA)Search on the Brink of Chaos
Daniel Panario (Carleton University, Canada)Polynomials over Finite Fields: Algorithms and Randomness
Oliver Riordan (University of Oxford, England)Percolation on Graphs
Peter Winkler (Dartmouth, USA)The Automaton as Statistician
Before the conference a Mini-Summerschool with lectures by Nicolas Broutin (INRIA Rocquencourt), Christian Krattenthaler (Univ. Wien), Angelika Steger (ETH Züurich), and Wojciech Szpankowski (Purdue Univ.) took place during June 25-26, 2010.
Furthermore a poster session was organized with posters presented by Zareen Alamgir, Saira Karim, and Syed Husnine; Milan Bradonjic, Aric Hagberg, Nick Hengartner and Allon G. Percus; Boris Granovsky; Immanuel Halupczok and Jan-Christoph Schlage-Puchta; Madhu Jain and G.C. Sharma; Daniel Krenn; Manfred Madritsch; Dimbinaina Ralaivaosaona; Alexey Ustinov; Martin Zeiner.
We express our gratitude to the members of the Programme Committee for their careful selection of the 41 contributed papers. This eventually guaranteed the high quality and the wide range of topics of the conference. We thank the members Steering Committee and the members of the Organisation Committee for the organizational work. Furthermore, we thank all the invited speakers, the authors of papers or posters, and all the participants of the conference. We are also grateful to the editor-in-chief of DMTCS Jens Gustedt and to Cyril Banderier for technical assistance during the compilation of the proceedings.
Last but not least we express our special thanks to the Austrian Science Foundation FWF, the City of Vienna as well as the Vienna University of Technology for the financial support of the conference.

This volume contains the selected "full" papers presented at AUTOMATA 2010, the 16th inter- national workshop on cellular automata and discrete complex systems. The workshop was held on June 14-16, 2010, at the LORIA laboratory in Nancy, France. AUTOMATA is an annual workshop on the fundamental aspects of cellular automata and related discrete dynamical sys- tems. The spirit of the workshop is to foster collaborations and exchanges between researchers on these areas. The workshop series was started in 1995 by members of the Working Group 1.5 of IFIP, the International Federation for Information Processing. The program committee consisted of 25 international experts on cellular automata and related models, and the selection was based on 2-4 peer reviews on each paper. Papers in this volume represent a rich sample of current research topics on cellular automata and related models. The papers include theoretical studies of the classical cellular automata model, but also many investigations into various variants and generalizations of the basic concept. The versatile nature and the flexibility of the model is evident from the presented papers, making it a rich source of new research problems for scientists representing a variety of disciplines.
As the editors of these proceedings, we thank all contributors to the scientific program of the workshop. We are especially indebted to the invited speakers and the authors of the contributed papers. We would also like to thank the members of the Program Committee and the external reviewers of the papers.

FPSAC 2009 was held at the Research Institute for Symbolic Computation, Hagenberg, Austria, on July 20-24, 2009.

This Proceedings volume is devoted to the 21st International Conference on Formal Power Series and Algebraic Combinatorics, held at the Research Institute of Symbolic Computation (RISC) in Hagenberg, Austria, during 20-24 July 2009. The conference was extremely well attended: 200 graduate students, junior researchers, and senior researchers from Austria, Canada, Colombia, China, Czech Republic, Denmark, France, Germany, Greece, Iceland, Israel, Italy, Japan, Mexico, Poland, Portugal, Slovenia, Spain, South Africa, South Korea, Sweden, the United Kingdom, and the United States gathered to enjoy the overwhelming hospitality of the RISC Combinatorics Group.
The conference programme featured nine invited lectures, given by Alexander Barvinok, Karin Erdmann, Jaroslav Nesetril, Bruno Salvy, Carsten Schneider, Michael Singer, Frank Sottile, Volkmar Welker, and Ae Ja Yee, 26 contributed talks, and 48 poster presentations. This volume contains the extended abstracts for most of the contributed papers and poster presentations, all of which had been selected in a careful reviewing process by the programme committee from submissions. These extended abstracts show the wide range of topics presented at the conference, linked together by the overall theme of Formal Power Series and Algebraic Combinatorics. These included enumeration, combinatorial geometry, commutative algebra, algebraic geometry, combinatorial representation theory, Hopf algebras, computational complexity, algebraic graph theory, and, of course (genius loci!), computer algebra. We thank all contributors and participants for having made this conference a show-case of current trends in the field and a lively place of exchange of ideas.
The organizers are very grateful for the financial support of the Johannes Kepler University Linz, the Austrian Science Foundation FWF, the province of Upper Austria, the University Fund Linz (Linzer Hochschulfonds), the Austrian Ministry of Science, the US National Science Foundation (NSF), and the US National Security Agency (NSA). They made it possible, with Susanna Fishel as manager, that a large number of young researchers could profit from this conference, respectively present their work. Funds generously provided by Elsevier were allocated to the Elsevier award for best extended abstract by a student (Guillaume Chapuy).
We would like to thank all of those who served on the Programme and Organising Committees, without whose contribution such a conference could never have been held. Furthermore, the help of Tanja Gutenbrunner, Gabriela Hahn, Veronika Pillwein, Marion Schimpl, and Ralf Hemmecke was more than invaluable to the local organizers.
