Abstract: The six papers in this issue are based on work presented
at the 15th British Colloquium for Theoretical Computer Science
(BCTCS) held at the University of Keele in April 1999 and organised by
John Stell. Although BCTCS has been running for a number of years, the
Keele colloquium is the first for which participants have been able to
submit papers for publication giving more detailed treatments of contributions
to the meeting. The papers in this issue provide a good overview of the
typical areas that are covered by the meeting and it is hoped that the
procedures inaugurated at BCTCS15 will be continued, particularly in view
of the quality of the articles that resulted. The editors are glad to take
this opportunity to extend their thanks to all those who supported the
issue by deciding to submit papers for consideration.
1 The BCTCS a Brief History
The first meeting of the British Colloquium for Theoretical Computer
Science was held in 1985 and hosted by the University of Leeds. This was
initiated by John Tucker, primarily as a forum for theoreticians based
in U.K. universities to meet and describe current research. One of the
most important aims of this and the subsequent colloquia has been to offer
a means by which postgraduate students can gain experience of presenting
work and discussing this with established researchers. In order to encourage
such participation the organisers have endeavoured to foster an informal
atmosphere and have ensured that individuals who wish to present talks
can be accommodated in the programme.
The colloquium has been held annually, usually around Easter, following
the success of the inaugural meeting at Leeds, and has been hosted by most
of the British universities with strong interests in theoretical computer
science.
Since the 1988 colloquium at the University of Edinburgh, it has become
customary to arrange a series of invited presentations in addition to the
submitted contributions. As well as leading U.K. based figures, these have
usually included at least one speaker from outside Britain. Over the past
few years this has provided occasion for research students to benefit from
the experience of figures such as, to select only a few, Les Valiant (1988,2000),
Joseph Goguen (1989), Philippe Flajolet (1990), Henk Barendregt (1991),
Paul Spirakis (1994), Jacobo Toran (1996) and Glynn Winskel (1999).
The present structure of the BCTCS was agreed following the formal
adoption of the BCTCS Constitution at BCTCS13 at the University Of
Sheffield in 1997, in which the aims of the colloquium are set
out. The move towards allowing a more permanent record of
contributions, in published form, was agreed upon following
discussions taken at BCTCS14 at the University of St. Andrews in
1998.
While the colloquium is primarily intended to provide a basis for
theoreticians working in the U.K., it warmly welcomes presentations
from researchers working outside Britain, and most meetings have
benefited from talks offered by participants who have travelled from
other European countries and further, in order to contribute
work.
A fuller description of the activities of the BCTCS, including details
of previous colloquia and invited talks, may be found on the BCTCS
Web site [1]. The next colloquium (BCTCS17) will be
hosted by the University of Glasgow between April 9th and April 12th, 2001.
Some preliminary information concerning this may be found at the colloquium
Web page [2].
