We consider the problem of minimizing regret with respect to a given set S of pairs of time selection functions and modifications rules. We give an online algorithm that has O( √ T log |S|) regret with respect to S when the algorithm is run for T time steps and there are N actions allowed. This improves the upper bound of O( √ TN log(|I||F|)) given by Blum and Mansour [BM07a] for the case when ...

Upper bounds are given for the complexity of two very natural randomized algorithms for finding the sink of an Acyclic Unique Sink Orientation (AUSO) of the ncube. For Random-Edge, we obtain an upper bound of about 1.80n, improving upon the the previous upper bound of about 2n/nlogn obtained by Gärtner and Kaibel. For Random-Jump, we obtain an upper bound of about (3/2)n, improving upon the pre...

Linial, Mansour and Nisan [7] proved that a function computed by a small-depth circuit of limited size has most of its Fourier support on small sets. We improve their bounds. When the bottom fanin is bounded we use essentially their argument, but to reduce the general case to this case without a loss in the asymptotic bounds requires a new argument. Warning: Essentially this paper is accepted f...

Diana Mansour, in her commentary1 in the July 2011 issue of this Journal, pointed out the inadequacy of the wording of the emergency contraception advice in the Medicines and Healthcare products Regulatory Authority’s Combined Oral Contraceptives (The Pill): When to Start Taking The Pill, and Missed Pill Advice.2 We also need to remember the women who have forgotten one pill in the week before ...
