Abstract. The problem of finding a large independent set in a hyper­
graph by an online algorithm is considered. We provide bounds for the
best possible performance ratio of deterministic vs. randomized and non­
preemptive vs. preemptive algorithms. Applying these results we prove
bounds for the performance of online algorithms for routing problems
via fixed paths over networks.
1 Introduction
The problem of finding the maximum independent set in a graph is a funda­
mental problem in Graph Theory and Theoretical Computer Science. It is well
