STOCHASTIC INPUT MODELS FOR ONLINE COMPUTING

In this paper, we study twelve stochastic input models for online problems and reveal the differences between their competitive ratios models. The ratio is defined as worst expected optimal value profit of solution obtained by algorithm, where distribution restricted according to model. Our purpose clarify difference among from view ratio. To handle a broad class problems, use framework called request-answer games, which were introduced Ben-David et al. fit into two categories: known unknown distribution. We consider six natural classes each category: dependent distributions, deterministic input, independent identical distribution, random order distributions. Using model, fundamental are variants secretary problem prophet inequality problem. these observe in
