Simulated annealing has proven to be a good technique for solving hard combina-torial optimization problems. Some attempts at speeding up annealing algorithms have been based on shared memory multiprocessor systems. Also parallelizations for certain problems on distributed memory multiprocessor systems are known. In this paper, we present a problem independent general purpose parallel implement...

In this paper we describe the distribution problems faced by one of the largest retailers in the distribution and sale of fast moving consumer goods in the U.K. The paper describes an initial solution method, which is then improved by a novel form of simulated annealing. A computational experiment for the improvement algorithm has been also carried out in order to illustrate the flexibility of ...

This paper considers the Economic Lot Scheduling Problem, that is, the problem of scheduling several products on a single facility so as to minimize holding and setup costs. Combination of frequency and timing as well as production quantity make this problem Np-hard. A heuristic is developed to obtain a good solution to ELSP. The proposed heuristic makes use of the Simulated Annealing Technique...

Electron Beam Annealing In article number 2300178, Heo and co-workers improved the power conversion efficiency stability of organic photovoltaics by applying an electron beam annealing process to solution-based ZnO as transport layer. The electrons extracted from Ar plasma were irradiated contribute improvement removing impurities improving density thin film.

Article history: Received: 13.2.2015. Received in revised form: 24.3.2015. Accepted: 27.3.2015. In structural design optimization method, numerical techniques are increasingly used. In typical structural optimization problems there may be many locally minimum configurations. For that reason, the application of a global method, which may escape from the locally minimum points, remains essential....

Proteins or genes that have similar sequences are likely to perform the same function. One of the most widely used techniques for sequence comparison is sequence alignment. Sequence alignment allows mismatches and insertion/deletion, which represents biological mutations. Sequence alignment is usually performed only on two sequences. Multiple sequence alignment, is a natural extension of two-se...

We report experimental study of phosphorus desorption from epi-ready InP(001) substrates during high-temperature annealing in an arsenic flux. InPAs solid solution and InAs islands are formed on the surface process annealing. The original method is proposed to determine amount atoms desorbing by determining islands. flux increases 1·10 -4 monolayer · cm -2 ·s -1 at 500 o C temperature 7.3·10 s ...

This work presents a heuristic approach proposed by one of the finalists of the Third International Timetabling Competition (ITC2011). The KHE school timetabling engine is used to generate an initial solution and then Simulated Annealing (SA) and Iterated Local Search (ILS) perform local search around this solution.

AISI 316 stainless steels were coated with 250 nm Ni film by electron beam deposition and post-annealed at different temperatures with a nitrogen flow of 600 cm3min-1 nitrogen. The prepared samples were corrosion tested in 1.0 M sulphuric acid solution using potentiodynamic technique. Crystallographic and morphological structure of the samples were analyzedanalysed by X-ray diffraction (XRD) an...
