This book constitutes the refereed proceedings of the 11th International Conference on Similarity Search and Applications, SISAP 2018, held in Lima, Peru, in October 2018.The 16 full papers presented together with 3 short papers and 1 demonstration paper were carefully reviewed and selected from 31 submissions. The papers deal with issues surrounding the theory, design, analysis, practice, and application of content-based and feature-based similarity search. They are organized in the following topical sections: metric search; visual search; nearest neighbor queries; clustering and outlier detection; graphs and applications; and shared session SISAP and SPIRE.

This book constitutes the refereed proceedings of the 12th Latin American Symposium on Theoretical Informatics, LATIN 2016, held in Ensenada, Mexico, in April 2016. The 52 papers presented together with 5 abstracts were carefully reviewed and selected from 131 submissions. The papers address a variety of topics in theoretical computer science with a certain focus on algorithms (approximation, online, randomized, algorithmic game theory, etc.), analytic combinatorics and analysis of algorithms, automata theory and formal languages, coding theory and data compression, combinatorial algorithms, combinatorial optimization, combinatorics and graph theory, complexity theory, computational algebra, computational biology, computational geometry, computational number theory, cryptology, databases and information retrieval, data structures, formal methods and security, Internet and the web, parallel and distributed computing, pattern matching, programming language theory, and random structures.

This book constitutes the refereed proceedings of the 19th International Symposium on String Processing and Information Retrieval, SPIRE 2012, held in Cartagena de Indias, Colombia, in October 2012. The 26 full papers, 13 short papers, and 3 keynote speeches were carefully reviewed and selected from 81 submissions. The following topics are covered: fundamentals algorithms in string processing and information retrieval; SP and IR techniques as applied to areas such as computational biology, DNA sequencing, and Web mining.

The 4th International Conference on Ad-Hoc Networks and Wireless (ADHOC- NOW 2005)was held October 6 8,2005in Cancun, Mexico. Adhoc Now started as a workshop in 2002 and was held at the Fields Institute in Toronto. In 2003, it was held in Montreal, and in 2004 it was held in Vancouver. 2005 was the ?rst yearfortheconferencetomoveoutsideofCanada.Thepurposeoftheconference is to create a collaborative forum between mathematicians, computer scientists, and engineers for research in the ?eld of mobile ad hoc and sensor networks. In 2005, we received over 100 submissions from 22 di?erent countries: Australia, Canada, China, France, Germany, Greece, India, Ireland, Italy, Japan, Korea, Malaysia, Mexico, Nepal, Nigeria, Pakistan, Poland, Spain, Sweden, Tunisia, the UK, and the USA a true international conference. Of the papers submitted, we selected 27 for presentation at the conference and publication in the proceedings. We are grateful to our Technical Program, Organizing, and Steering C- mittees; without their help, expertise, and experiencewe could not haveselected such a ?ne program. We thank Jorge Urrutia of the Instituto de Matem aticas, Universidad NacionalAut onoma de M exico, and J.J. Garcia-Luna-Acevesof the Computer Engineering Department, University of California, Santa Cruz for - cepting our invitation to speak at the conference. Special thanks are due to the crewfromtheFacultaddeCienciasF ?sico-Matem aticasUniversidadMichoacana for handling the local arrangements, and to the Mobile Adhoc Research Lab at Arizona State University for handling odd jobs on a moment s notice."

This volume constitutes the proceedings of the 2nd Atlantic Web Intelligence Conference(AWIC2004).TheconferencewasheldinthecityofCancun,Mexico, a setting that inspired lively discussions andre?ections onopen issues facing the ?eld of Web intelligence. TheAWICconferences havebeenmotivated by advancesinthe ?eld ofart- cialintelligenceandthechallengesfacingtheirapplicationtoWeb-basedsystems. With this second edition, AWIC provided a forum for specialists from di?erent disciplines of computer science to exchange their experiences and ideas in this growing ?eld of research. The selection of papers followed a strict, double-blind refereeing process by a renowned international committee. We received 57 contributions, with ?rst authors from 15 di?erent countries, from which 22 papers were selected to be presented and published in this proceedings volume. We thank all members of the Program Committee for their valuable reviews of the papers. In addition, we were pleased to have as invited speakers Dr. Prabhakar Raghavan, Chief Scientist and Vice President of Emerging Technologies in Verity, Inc. and Consulting Professor of Computer Science at Stanford Univ- sity, and Prof. C. Lee Giles, Davide Reese Professorof the School of Information Sciences and Technology at The Pennsylvania State University. Abstracts of their lectures are included in these proceedings. In putting together this conference, we had the pleasure of working with an outstanding group of people. We thank them all for their hard work on behalf of this conference. In particular we would like to thank Manuel Montes y Gomez, ' Director of the Mexico Research Centre of the Web Intelligence Consortium, Elisa Moran, Marcela Rodr' ?guez, and Jorge Niebla.

Thisvolumecontainsthe paperspresentedatthe 17thInternationalSymposium on String Processing and Information Retrieval (SPIRE 2010), held October 11-13, 2010 in Los Cabos, Mexico. The annual SPIRE conference provides researchers within ?elds related to string processing and/or information retrieval a possibility to present their or- inal contributions and to meet and talk with other researchers with similar - terests. The call for papers invited submissions related to string processing (d- tionary algorithms; text searching; pattern matching; text and sequence c- pression; automata-based string processing), information retrieval (information retrieval models; indexing; ranking and ?ltering; querying and interface design), natural language processing (text analysis; text mining; machine learning; - formation extraction; language models; knowledge representation), searchapp- cations and usage (cross-lingual information access systems; multimedia inf- mation access; digital libraries; collaborative retrieval and Web-related appli- tions; semi-structured data retrieval; evaluation), and interaction of biology and computation (DNA sequencing and applications in molecular biology; evolution andphylogenetics;recognitionofgenesandregulatoryelements;sequencedriven protein structure prediction). The papers presented at the symposium were selected from 109 submissions written by authors from 30 di?erent countries. Each submission was reviewed by at least three reviewers, with a maximum of ?ve reviews for particularly challengingpapers. The ProgramCommittee accepted 39 papers(corresponding to ?35% acceptance rate): 26 long papers and 13 short papers. In addition to these presentations, SPIRE 2010 also featured invited talks by Gonzalo Navarro (Universidad de Chile) and Mark Najork (Microsoft Research, USA).
