We propose an algorithm for multistage stochastic linear programs with recourse where random quantities in di erent stages are independent. The algorithm successively approximates expected recourse functions by building up valid cutting planes to support these functions from below. In each iteration, for the expected recourse function in each stage, one cutting-plane is generated using the dual...

Algorithmic fairness is typically studied from the perspective of predictions. Instead, here we investigate recourse actions suggested to individuals remedy an unfavourable classification. We propose two new fair-ness criteria at group and individual level, which—unlike prior work on equalising average group-wise distance decision boundary—explicitly account for causal relationships between fea...

We consider the bin packing problem in a fully-dynamic setting, where new items can arrive and old items may depart. The objective here is to obtain algorithms achieving low asymptotic competitive ratio while changing the packing sparingly between updates. We associate with each item i a movement cost ci ≥ 0. We wish to achieve good approximation guarantees while incurring a movement cost of β ...

ghassan kanafani was the author, critic, poet, martyr and playwriter who studies human being issues by his stories. he condemns whatever causes palestine’s tragedy in his “men in the sun” novel. there is no waste and extra word or sentence in this novel and the author does not recourse slogan and his position is clear among his novel. in this novel the men can understand cruelty under the gover...

This paper addresses the problem of maximizing the expected size of a matching in the case of unreliable vertices and/or edges. The assumption is that upon failure, remaining vertices that have not been matched may be subject to a new assignment. This process may be repeated a given number of times, and the objective is to end with the overall maximum number of matched vertices. The origin of t...
