Editor's Letter It is interesting to note t h a t in this, the first year of what the popular press describe as the new millennium, the ACM is in the throes of creating a digital library containing all ACM publications, including back-issues of newsletters such as 5 I G A C T News. While back-issues of ,.qIGACT News are already available on-line to S I G A C T members at http://sigact, aem. o r g / s i g a c t n e w s / o n l i n e . h t m l as far back as Issue 100, we look forward to a time soon when all issues m a y be available. Contributors to S I G A C T News are encouraged to read the Notice to Past Authors of A C M - P u b l i s h e d Articles on p. 88 of this issue, particularly if t h e y do not want their contribution to appear in the A C M Digital Library. Ian Parberry, Editor Quarterly Quote T h e Reader may here observe the Force of Numbers, which can be successfully applied, even to those things, which one would imagine are subject to no Rules. There are very few things which we know, which are not capable of being reduc'd to a M a t h e m a t i c a l Reasoning; and when t h e y cannot it's a sign our knowledge of t h e m is very small and confus'd; and when a M a t h e m a t i c a l Reasoning can be had it's as great a folly to make use of any other, as to grope for a t h i n g in the dark, when you have a Candle standing by you. - - J o h n A r b u t h n o t (1692) Mission S t a t e m e n t The primary mission of SIGA CT is to foster and promote the discovery and dissemination of high quality research in the domain of theoretical computer science. The field of theoretical computer science is interpreted broadly so as to include algorithms, data structures, complezity theory, parallel computation, distributed computation, information theory, cryptography, program semantics and verification, machine learning, computational biology, VLSI, computational geometry, computational number theory and algebra, and the study of randomness. Work in this field is often distinguished by its emphasis on mathematical technique and rigor.
