On Asymptotically Optimal Approach for?the Problem of Finding Several Edge-Disjoint Spanning Trees o undirected graphs turned out to be impossible due to the issues associated with the summation of dependent random variables. In this work we give an .-time algorithm with conditions of asymptotic optimality for the case of undirected graphs.

On Some Variants of the Merging Variables Based (1+1)-Evolutionary Algorithm with Application to Maxer worst case estimation than the original (1+1)-EA. In the experimental part we conduct comparison of the proposed strategy with several known variants of (1+1)-EA and demonstrate its practical applicability for a number of hard instances of MaxSAT problem.

A Column Generation Based Heuristic for a Temporal Bin Packing Problemo get lower and upper bounds. Preliminary computational experiments for real test instances indicate a small gap between the bounds. The average relative error is at most 0.88% for one week planning horizon and about 50000 items. The average running time is 21?s for a personal computer.

On the Computational Efficiency of?Catalyst Accelerated Coordinate Descentension . in . times and, in practice, demonstrates a faster convergence in comparison with standard methods. As an example of applying the proposed approach, it was shown a variant of obtaining on its basis some efficient methods for optimizing Markov Decision Processes (MDP) in a minimax formulation with a Nesterov smoothed target function.
