William F. (Bill) Smyth                

Welcome to my home page!
You are Visitor No. 113074 since 1 December 2001.

Regarded at its birth in 2007 as a one-off event, StringMasters seems to be here to stay. Since 2007 it has been held at least once every year at a large variety of places: Perth, Western Australia; Stellenbosch, South Africa; Palermo & Verona, Italy; Prague, Czech Republic; Rouen, France; Warsaw, Poland; and several times more at McMaster University. In 2015 for the first time it was sponsored by the Centre for Combinatorics on Words & Applications (CCWA) of Murdoch University, Western Australia.

Papers emerging from StringMasters 2007 & 2008 were published in a special issue 97-3 (2009) of Fundamenta Informaticae. Papers coming out of the 2009-2011 StringMasters meetings appeared in Journal of Discrete Algorithms 10 (2012) and JDA 20 (2013); a special issue of the same journal published papers from the 2012-2013 meetings.

Please take note that the International Workshop on Combinatorial Algorithms held its 2017 meeting 17-21 July in Newcastle, Australia, to commemorate Mirka Miller, one of the founders of IWOCA, my old friend and colleague, who passed away in January 2016.

IWOCA 2018 was held at NUS in glamorous Singapore, organized by Wing-Kin (Ken) Sung.

In July 2019 IWOCA was held in Pisa, Italy, under the supervision of Roberto Grossi & Nadia Pisanti.

Then in 2020, the year of the pandemic, IWOCA, under the supervision of Ralf Klasing, went on-line, one of the first scientific gatherings to do so. Originally scheduled to be held 08-10 June at the Université de Bordeaux, it was held on time as described here.

In 2021, cosupervised by Vida Dujmovic, Paola Flocchini and Lucia Moura, IWOCA returned to Canada for the first time since 2011.

In 2022 IWOCA 33 will be held at the University of Trier, Germany, co-chaired by Cristina Bazgan and Henning Fernau.

To mark my 80th birthday (a long time ago now), Theoretical Computer Science published a special issue on Stringology.
