The history of DIMACS shows its strong commitment to
combinatorial and algorithmic geometry. It is a major area of interest
among researchers at both DIMACS and DIMATIA. So, it seems natural to
follow up this interest and the DIMACS Special Year on Discrete and Computational Geometry and DREI programs
with a focused workshop in this area, and we have chosen the topic
Combinatorial and Algorithmic Geometry. The twin effect
of randomization and derandomization in computational geometry has
been spectacular. A whole new theory of deterministic sampling has
been developed recently, and as a result, several outstanding open
problems have been solved (e.g., optimal algorithms for convex hulls,
and fixed-dimensional convex programming). Books and surveys have
been written to report these exciting developments -- see Chazelle
[1995], Clarkson [1992], Matousek [to appear], Mulmuley [1994]. Given
the central contributions of Czech and US scientists to this recent
work, it would seem timely and appropriate to organize a focused
workshop on the topic of Probabilistic Techniques in Computational
Geometry.
