During the past few decades the gradual merger of Discrete Geometry and the newer discipline of Computational Geometry has provided enormous impetus to mathematicians and computer scientists interested in geometric problems. This 2005 volume which contains 32 papers on a broad range of topics of interest in the field is an outgrowth of that synergism. It includes surveys and research articles exploring geometric arrangements polytopes packing covering discrete convexity geometric algorithms and their complexity and the combinatorial complexity of geometric objects particularly in low dimension. There are points of contact with many applied areas such as mathematical programming visibility problems kinetic data structures and biochemistry as well as with algebraic topology geometric probability real algebraic geometry and combinatorics.
