Abstract Variable-length encoding evolutionary algorithm has been proved effective in small and medium-sized reversible logic synthesis. chromosome is adopted because the length of optimal circuit unknown. However, it leads to huge search space. The improved two-stage hybrid synthesis proposed reduce space enhance feasible ratio. Fixed variable-length are applied two stages respectively. Estima...

The problem of scheduling in a Flow Shop with Multiple Processors (FSMP) is considered with the objective of minimizing the makespan for static problems. Herein, the usefulness of simulated annealing (SA) is investigated. Two stages are used in generating the makespans. A good initial-heuristic-seed sequence, obtained in the first stage, is improved-upon in the second stage by the SA technique....

In this paper, we present a novel two-stage framework of designing a noise-robust front-end for automatic speech recognition. In the first stage, a parametric model of acoustic distortion is used to estimate the clean speech and noise spectra in a principled way so that no heuristic parameters need to set manually. To reduce possible flaws caused by the simplifying assumptions in the parametric...

university course timetabling is a complex optimizationproblem. there are many components like departments, faculties, rooms,and students making the problem huge and difficult to solve. eachcomponent enforces a set of normally conflicting constraints on thesolution space. the problem will be solved if courses are scheduled indifferent rooms and within some specific time slots such that a set of...

Two-stage selection procedures have been widely studied and applied in determining the required sample size (i.e., the number of replications or batches) for selecting the best of k designs. The Enhanced Two-Stage Selection (ETSS) procedure is a heuristic two-stage selection procedure that takes into account not only the variance of samples, but also the difference of sample means when determin...

In this work we present the sequential and parallel versions of a heuristic algorithm for the solution of a two-stage stochastic mixed 0-1 model for closed loop supply chain planning problem along a time horizon. Some computational experience conducted on randomly generated networks shows the quality of the proposed approach.

many studies have been conducted to determine the efficiency of two-stage network structures in the recent years. the two-stage network with additional inputs to the second stage, in which the second stage is independent of the first stage are one of these structures. thus, there is a need for a model capable of calculating the efficiency of two-stage structures as well as efficiency of each st...
