This volume presents a collection of refereed papers reflecting the
state of the art in the area of over-constrained systems.
Besides 11 revised full papers, selected from the 24 submissions to the
OCS workshop held in conjunction with the First International Conference
on Principles and Practice of Constraint Programming, CP '95, held in
Marseilles in September 1995, the book includes three comprehensive
background papers of central importance for the workshop papers and the
whole field. Also included is an introduction by one of the volume
editors together with a bibliography listing 243 entries. All in all
this is a very useful reference book relevant for all researchers and
practitioners interested in hierarchical, partial, and over-constrained
systems.
