Abstract

The fractional knapsack problem is one of the classical problems in combinatorial optimization, which is well understood in the offline setting. The corresponding online setting has been handled only briefly in the theoretical computer science literature so far, although it appears in several applications. In this talk, I present an algorithm for the online fractional knapsack problem in the popular random order model that admits a competitive ratio of 4.39. This result significantly improves over the previously best known competitive ratio of 9.37 and surpasses the current best 6.65-competitive algorithm for the integral case.


This talk is based on joint work with Andreas Karrenbauer.
