Preface
This proceedings volume contains papers presented at IWOCA 2018, the 29th Inter-
nationalWorkshoponCombinatorialAlgorithms,heldduringJuly16–19,2018,atthe
DepartmentofComputerScience,NationalUniversityofSingapore(NUS),Singapore.
Theconferencecovereddiverseareasofcombinatorialalgorithms,namely,complexity
theory,graphtheoryandcombinatorics,combinatorialoptimization,cryptographyand
information security, algorithms on strings and graphs, graph drawing and labelling,
computational algebra and geometry, computational biology, probabilistic and ran-
domized algorithms, algorithms for big data analytics, and new paradigms of com-
putation. The conference was organized by the School of Computing, National
University of Singapore.
IWOCA is an annual conference series on all aspects of combinatorial algorithms.
The series of IWOCA conferences grew out of over 28 years of history. Initially, the
conferencewasalocalworkshopinAustralia,knownasAWOCA.In2007,itbecame
an international conference. Previous meetings have been held in Australia, Canada,
CzechRepublic,Finland,France,Indonesia,India,Italy,Japan,SouthKorea,UK,and
USA. IWOCA is led by a strong Steering Committee, whose members are Charles
Colbourn (Arizona State University), Costas Iliopoulos (King’s College), and Bill
Smyth(McMasterUniversity).TheProgramCommitteescomprisecomputerscientists
of international repute from different parts of the globe. Notably, the Program
Committee of IWOCA 2018 comprised 46 eminent researchers from Australia,
Bangladesh, Canada, Chile, China, Czech Republic, Finland, France, Greece, Hong
Kong, Israel, Italy, Japan, Malaysia, Norway, Singapore, Slovenia, Taiwan, UK, and
USA.
The technical program was finalized by selecting the highest-quality papers from
among 69 submitted papers. After a rigorous review followed by in-depth discussion
by the Program Committee, this year we could only accept 31 high-quality papers.
Among these 31 papers, we selected “Linear Ramsey Numbers” for the best paper
award, which presented at the conference. In addition to the 31 contributed talks, the
scientificprogramoftheworkshopincludedinvitedtalksbythreeeminentresearchers,
namely, Prof. Michael Fellows (University of Bergen, Norway), Prof. Sanjay Jain
(National University of Singapore, Singapore), and Prof. Kunihiko Sadakane
(University of Tokyo, Japan). We are extremely grateful to our invited speakers for
their excellent talks at the workshop. We thank all the authors who submitted their
worksforconsiderationtoIWOCA2018.Wedeeplyappreciatethecontributionofall

timely manner despite their extremely busy schedule. We would like to acknowledge
the EasyChair conference management system again for providing us with their cel-
ebrated platform for conference administration. We are grateful to Springer for

publishing the proceedings of IWOCA 2018 in the LNCS series. As always, we are
deeply indebted to the IWOCA Steering Committee for their continuous guidance,
support, and leadership. Above all, we are extremely grateful to the Organizing
Committee of IWOCA 2018 for making the event a grand success. Finally, we would
like to thanks Springer for sponsoring the conference.
