This volume contains the papers presented at the 6th International
Workshop on Randomization and Approximation Techniques in Computer
Science (RAN- DOM 2002), which took place at Harvard University,
Cambridge, Massachusetts, from September 13-15, 2002. RANDOM 2002 was
concerned with applications of randomness to computational and
combinatorial problems, and was the sixth workshop in the series
