The 25th International Computing and Combinatorics Conference (COCOON 2019) will be held in Xian, China during July 29-31, 2019. Original research papers in the areas of algorithms, theory of computation, computational complexity, and combinatorics related to computing are solicited. In addition to theoretical results, we are particularly interested in submissions that report on experimental and applied research of general algorithmic interest. Special consideration will be given to research that is motivated by real-world problems.

Lehrstuhl für Mathematik VII (Numerical Mathematics and Optimization), Universität Würzburg

The focus of this summer school is on recent developments in cryptography, graph theory, and their intersection. Topics are the distribution of products of two distinct prime numbers (as they are used for keys in RSA), an isogeny-based elliptic curve cryptosystem (as a candidate for post-quantum cryptography), and aspects of algebraic graph theory (e.g., the spectrum of graphs, expanders and Ramanujan graphs and their role in certain post-quantum cryptosystems). The Summer School is supported by the European Mathematical Society.

Between 29 July and 2 August 2019, the University of Birmingham will host the 27th British Combinatorial Conference, a biennial conference covering research in all areas of Combinatorics and its applications. This conference series has been running since 1969 and is the focal event in the UK Combinatorics calendar. The 2019 conference is organised in partnership with the Clay Mathematics Institute, the Heilbronn Institute and the London Mathematical Society (through a Scheme 1 grant); we thank each of these organisations for their generous involvement and support.

Graph searching focuses on the analysis of games and graph processes that model some form of intrusion in a network, and efforts to eliminate or contain that intrusion. For example, in the game of Cops and Robbers, a robber is loose on the network, and a set of cops attempts to capture the robber. How the players move and the rules of capture depend on which variant is studied. There are many variants of graph searching studied in the literature, which are either motivated by problems in practice or are inspired by foundational issues in computer science, discrete mathematics, and artificial intelligence, such as robotics and network security.

SPIRE 2019 is the 26th International Symposium on String Processing and Information Retrieval. SPIRE started in 1993 as the South American Workshop on String Processing and was held in Latin America until 2000 when SPIRE travelled to Europe and was held A Coruña, Spain. Nineteen years have gone, and SPIRE is back to Spain, this time allowing attendees to visit Segovia, a beautiful historical city located very close to Madrid that was declared World Heritage City by UNESCO in 1985.

Graph theory and combinatorics are closely related to many mathematical subjects, such as, topology, geometry and number theory and have a lot of applications in applied sciences, engineering and optimization problems. The workshop focuses on all aspects of graph theory, combinatorics and their applications. It dedicates to creating a platform for exchanging the latest research results; sharing the advanced research methods and latest trends in these areas and to build & develop further collaborations.

The TextGraphs series of workshops, now going on for more than a decade, have published and promoted the synergy between the field of Graph Theory (GT) and Natural Language Processing (NLP). The thirteenth edition of the TextGraphs workshop aims to extend the focus on graph-based and graph-supported machine learning and deep learning methods. We encourage the description of novel NLP problems or applications that have emerged in recent years, which can be addressed with existing and new graph-based methods.

These are a series of combinatorial workshops, held once per semester, each on a Saturday. The series began with its first meeting in spring 2010. They rotate among the universities in and around the Research Triangle. Participants come from numerous colleges and universities within a few hours drive, and some from even farther away. These workshops are funded by the National Science Foundation, in particular enabling us to bring in four exciting speakers to give one hour talks each time as well as funding travel expenses for participants.

Algebraic Combinatorics has recently been energized through inAAC2020_imageteractions with Probability, Mathematical Physics, and Theoretical Computer Science. Of great interest is how classical algebro-combinatorial objects behave when their defining parameters become large or random. This new perspective has birthed the rapidly developing subject of Asymptotic Algebraic Combinatorics, the subject of this workshop.

This workshop, sponsored by AIM and the NSF, will be devoted to the topology of configuration spaces of graphs.

Combinatorics is a branch of mathematics concerning the study of finite or countable discrete structures. It finds applications in various domains. In particular, due to advances in biotechnology, applications in biology and medical research have increased, many of which arose from the study of bio-molecular sequences and their interaction. This program aims to investigate the combinatorial problems in strings and graphs and their applications in biological science, hoping to explore new ideas and techniques in analyzing these big datasets.

At the conference we will be celebrating the 65th birthday of Paul Terwilliger. As such, the general theme of this conference will be the mathematical topics that Paul has worked on over the years (which all have relationships to the q-Onsager algebra).

The Young Researchers in Combinatorics workshop is aimed at PhD students and early-career academics working in Extremal and Probabilistic Combinatorics and related fields. By building an environment without senior researchers, we hope the participants will feel free to contribute their ideas openly, thus preparing them to undertake their own research projects. The workshop consists mostly of working sessions in which participants collaborate on research problems, and a limited number of talks and lectures. We aim to host around 10 invited participants and about 25 PhD students for a week between 19 and 25 July 2020 at ICMS Edinburgh. Accommodation and refreshments are provided for all participants, as well as a conference dinner. A registration fee of 100GBP is payable by all non-invited participants. We expect to start accepting applications in October 2019.
