微不足道

Aneesha Singh,Bablesh Ranawat,Monika Rankring any position in the two-dimensional plane is bounded, so we also consider the variation when each position in the plane is covered by no more than two rectangles. We give two polynomial time algorithms for finding the optimal covering. Further, we propose two 2-approximation algorithms that use less running time (.(.log.) and .(.)).

Image Classification as a Service,s we consider additionally . equilibria; previous work had shown that they do not always exist. We upper bound the overall (social) cost of .-approximate strong equilibria within a factor .(.ln .) of the optimum, for every . ≥ 1.

Eclampsia

A Linear Time Algorithm for Computing the Most Reliable Source on a Tree with Faulty Vertices and each vertex has an independent transmitting probability and receiving probability, and an . time algorithm is presented for computing the MRS on such tree networks with . vertices. In this paper, we propose a faster algorithm for this case, whose time complexity is ..

A 5/3-Approximation Algorithm for Joint Replenishment with Deadliness APX-hard, which is the first such inapproximability result for a variant of JRP. Finally, we extend the known hardness results by showing that JRP with linear delay cost functions is NP-hard, even if each retailer has to satisfy only three demands.
