Preface
This volume contains the proceedings of the 19th International Symposium on
AlgorithmsandComputation(ISAAC2008),heldontheGoldCoast,Australia,
December 15–17, 2008. In the past, it was held in Tokyo (1990), Taipei (1991),
Nagoya(1992),Hong Kong(1993),Beijing (1994),Cairns(1995),Osaka(1996),
Singapore (1997), Daejeon (1998), Chennai (1999), Taipei (2000), Christchurch
(2001), Vancouver (2002), Kyoto (2003), Hong Kong (2004), Hainan (2005),
Kolkata (2006), and Sendai (2007).
ISAACisanannualinternationalsymposiumthatcoverstheverywiderange
of topics in the field of algorithms and computation. The main purpose of the
symposium is to provide a forum for researchers working in algorithms and
theoryofcomputationfromallovertheworld.Inresponsetoourcallforpapers,
we received 229 submissions from 40 countries.The task of selecting the papers
in this volume was done by our Program Committee and many other external
reviewers. After an extremely rigorous review process and extensive discussion,
the Committee selected 78 papers. We hope all accepted papers will eventually
appear in scientific journals in a more polished form. Two special issues, one of
Algorithmica and one of the International Journal on Computational Geometry
and Applications, with selected papers from ISAAC 2008 are in preparation.
The best paper award was given to Takehiro Ito, Takeaki Uno, Xiao Zhou
and Takao Nishizeki for “Partitioning a Weighted Tree to Subtrees of Almost
Uniform Size.” Selected from seven submissions authored by students only, the
beststudentpaperawardwasgiventoLudmilaScharfandMarcScherfenbergfor
“Inducing Polygons of Line Arrangements.” Three prominent invited speakers,
TetsuoAsano,JAIST,Japan,PeterEades,UniversityofSydney,Australia,and
RobertTarjan,PrincetonUniversity,HP,USA,alsocontributedtotheprogram.
We would like to thank all the Program Committee members and external
reviewersfor their excellentwork,especially giventhe time constraints.We also
thank all those who submitted papers for consideration, thereby contributing
to the high quality of the conference. We would like to thank our supporting
organizations for their assistance and support. Finally, we are deeply indebted
to the Organizing Committee members whose excellent effort and professional
service to the community made the conference an unparalleled success.
