The Prophet Inequality - Brown University
In the theory of online algorithms and optimal stopping, a prophet inequality is a bound on the expected value of a decision-making process that handles a sequence of random inputs from known probability distributions, relative to the expected value that could be achieved by a "prophet" who knows all the inputs … Visa mer The classical single-item prophet inequality was published by Krengel & Sucheston (1978), crediting its tight form to D. J. H. (Ben) Garling. It concerns a process in which a sequence of random variables Visa mer • Matroid Prophet Inequalities and Mechanism Design, The Matroid Union Visa mer Various generalizations of the single-item prophet inequality to other online scenarios are known, and are also called prophet inequalities. Visa mer Prophet inequalities are related to the competitive analysis of online algorithms, but differ in two ways. First, much of competitive analysis assumes worst case inputs, chosen to maximize the ratio between the computed value and the optimal value that … Visa mer WebbSequential Posted Pricing, Prophet Inequality, and Random Bipartite Matching Ioannis Caragiannis1[0000 00024918 7131], Nick Gravin2[0000 3845 947X], Pinyan Lu2, and Zihe Wang3[0000 0001 7752 4687] 1 Department of Computer Science, Aarhus University, Aarhus, Denmark [email protected] 2 ITCS, Shanghai University of Finance and … palmaonfire

Webb19 juli 2024 · In the classic prophet inequality, samples from independent random variables arrive online. A gambler that knows the distributions must decide at each point in time whether to stop and pick the current sample or to … Webb21 maj 2024 · Matching is one of the most fundamental and broadly applicable problems across many domains. In these diverse real-world applications, there is often a degree of uncertainty in the input which has led to the study of stochastic matching models.

Matthew Weinberg. In the classical prophet inequality, a gambler observes a sequence of stochastic rewards and must decide, for each reward , whether to keep it and stop the game or to forfeit the reward forever and reveal the next value . エキスポシティ 印刷機
