In this article, we propose and evaluate three different state recovery algorithms aimed for Paxos-one of the most popular distributed agreement protocols. Paxos is commonly used to maintain consistency among machine replicas despite failures processes. The first algorithm, that call FullSS, originates from original requires system frequently uses stable storage during regular (non-faulty) execution. other two algorithms, ViewSS EpochSS, scarcely require access storage, recovering process...
This paper introduces a new approach to applying hyper-heuristic algorithms solve combinatorial problems with less effort, taking into account the modelling and algorithm construction process. We propose unified encoding of solution set low level heuristics which are domain-independent change itself. enables us address NP-hard generate good approximate solutions in reasonable time without large amount additional work required tailor search methodologies for problem hand. In particular, we...
