in this paper,  a heuristic algorithm is proposed in order to solve a nonlinear lexicography goal programming (nlgp) by using an efficient initial point. some numerical experiments showed that the search quality by the proposed heuristic in a multiple objectives problem depends on the initial point features, so in the proposed approach the initial point is retrieved by data envelopment analysis...

in this study, the tio2 nanorods were synthesized from p25 tio2 nanoparticles by hydrothermal method in 10 m naoh solution. the effects of annealing temperatures on produced nanorods were investigated  by scanning  electron microscopy (sem) x-ray diffraction (xrd) and photoluminescence (pl) spectroscopy. diameter growth and  changes  of  surface  oxygen  defects of  synthesized nanorods are stu...

The effects of the solution-annealing temperature on the precipitation of secondary phases and the associated pitting corrosion resistance in hyper duplex stainless steel after aging at 1123K were investigated in a highly concentrated chloride solution. Increasing the solution annealing temperature from 1333 to 1413K retarded the formation of the secondary phases owing to a decrease in both the...

An implementation for parametric snakes used for object tracking is proposed via generalized deterministic annealing (GDA). Given an arbitrary energy functional that quantifies the quality of the contour solution, GDA computes the snake position by approximating the solution given by stochastic simulated annealing. First, the Markov chain representing the solution space for the snake position i...

This paper proposes simulated annealing based algorithm for the synthesis of a finite state machine to determine the optimal state assignment with less area and power dissipation. The algorithm has two annealing stages. In the first rough annealing stage it tries to search in global scope by the proposed rough search method. In the second focusing annealing stage it tries to search in local sco...

A Simulated Annealing method is presented for the solution of nonlinear time series estimation problems, by maximization of the a Posteriori Likelihood function. Homogeneous temperature annealing is proposed for smoothing problems and inhomogeneous temperature annealing for filtering problems. Both methods of annealing guarantee convergence to the Maximum A Posteriori Likelihood (MAP) estimate....

We define Genetic Annealing as simulated annealing applied to a population of several solutions when candidates are generated from more than one (parent) solution at a time. We show that such genetic annealing algorithms can inherit the convergence properties of simulated annealing. We present two examples, one that generates each candidate by crossing pairs of parents and a second that generat...

in this paper, we introduce a methodology for safety stock placement in supply chain. the problem has two objectives: minimization of good's delivery time and inventory cost. because the problem belongs to np-hard category, we develop a proper simulated annealing algorithm (sa) for solve the proposed methodology in large scaled problem. for verify the performance and efficiency of the meth...
