Probabilistic analysis of Online Bin Coloring algorithms via Stochastic Comparison
Benjamin Hiller, Tjark Vredeveld · RePEc: Research Papers in Economics · 2008
This paper proposes a new method for probabilistic analysis of online algorithms that is based on the notion of stochastic dominance. We develop the method for the Online Bin Coloring problem introduced in [15]. Using methods for the stochastic comparison of Markov chains we establish the strong result that the performance of the online algorithm GreedyFit is stochastically dominated by the performance of the algorithm OneBin for any number of items processed. This result gives a more realistic picture than competitive analysis and explains the behavior observed in simulations. 1
