This large, distributed, and everchanging network poses a challenge to researchers: How does one study, model, or und- stand such a decentralized, constantly evolving entity? Research in large-scale networks seeks to address this question, and the unique nature of these networks calls for a range of techniques from a host of disciplines. The workshop Com- natorial and Algorithmic Aspects of Networking and the Internet (CAAN 2004) provided a forum for the exchange of ideas on these topics. The primary goals of the workshop were to bring together a diverse cro- section of researchers in an already scattered and distinct community and also to provide a snapshot of the cutting-edge research in this ?eld.We succeeded in these goals: among the participants were mathematicians, computer scientists in theory and algorithms, computer scientists in networks, physicists, and en- neers, as well as researchers from Europe and North America, participants from industry and academia, students, and established researchers; and among the papers were some new and surprising results as well as some introductions to the foundations of the ?eld.

The papers in this volume were presented at the 9th Workshop on Algorithms and Data Structures (WADS 2005). The workshop took place during August 15 - 17, 2005, at the University of Waterloo, Waterloo, Canada. The workshop alternateswith the ScandinavianWorkshopon Algorithm Theory(SWAT), c- tinuing the traditionof SWAT and WADS startingwith SWAT 1988and WADS 1989. From 90 submissions, the Program Committee selected 37 papers for p- sentation at the workshop. In addition, invited lectures were given by the f- lowing distinguished researchers: Allan Borodin and Max J. Egenhofer. OnbehalfoftheProgramCommittee,wewouldliketoexpressoursincere- preciation to the many persons whose e?ort contributed to making WADS 2005 a success. These include the invited speakers,members of the ste- ing and ProgramCommittees, the authors who submitted papers, and the many referees who assisted the ProgramCommittee.

The papers contained in this volume were presented at the 9th Latin American TheoreticalInformaticsSymposiumheldattheBenitoJu' arezUniversityofO- aca, Oaxaca City, M' exico, April 19-23, 2010. The LATIN series of conferences was launched in 1992 to foster the interaction between the Latin American t- oretical computer science community and computer scientists around the world. LATIN 2010wasthe ninth ofa series,after SaoPaulo,Brazil(1992);Valparaiso, Chile (1995); Campinas, Brazil (1998); Punta del Este, Uruguay (2000); C- cun, Mexico (2002); Buenos Aires, Argentina (2004); Valdivia, Chile (2006) and B' uzios, Rio de Janeiro, Brazil (2008). From the 155 submissions, the Program Committee selected 56 papers for presentation at the conference. The selectionofpaperswasbasedonoriginality, quality, and relevance to theoretical computer science. It is expected that most of these papers will appear in a more complete and polished form in scienti?c journalsinthefuture.Inadditiontothecontributedpapers,thisvolumecontains the abstracts of four invited plenary talks given at the conference by Cristopher Moore, Piotr Indyk, Sergio Rajsbaum, and Leslie Valiant.A special session on the life and work of the late Imre Simon was held. Prof. Simon played a key role in the development of theoretical computer science in Latin American as well as theLATINconference.ThissessionhadcontributionsfromRicardoBaeza-Yates, John Brzozowski, Volker Diekert, and Jacques Sakarovitch.

This Festschrift volume, published in honour of J. Ian Munro, contains contributions written by some of his colleagues, former students, and friends. In celebration of his 66th birthday the colloquium "Conference on Space Efficient Data Structures, Streams and Algorithms" was held in Waterloo, ON, Canada, during August 15-16, 2013. The articles presented herein cover some of the main topics of Ian's research interests. Together they give a good overall perspective of the last 40 years of research in algorithms and data structures.
