Genetic algorithm is widely used in optimization problems for its excellent global search capabilities and highly parallel processing capabilities; but, it converges prematurely and has a poor local optimization capability in actual operation. Simulated annealing algorithm can avoid the search process falling into local optimum. A hybrid genetic algorithm based on simulated annealing is designe...

The accurate synthesis of binary porous media is a difficult problem. Initial applications of simulated annealing in this context with small data sets and simple energy functions have met with limited success. Simulated annealing has been applied to a wide variety of problems in image processing. Particularly in scientific applications such as discussed here, the computational complexity of thi...

Annealing of general iterative stochastic schemes is studied by using Wentzell’s large deviation theory. The convergence of this algorithm is shown under some conditions. The closed form of the critical constant is specified in terms of its potential function of the mean model.

The density of optical glass varies from 2.39 for N-BK10 to 6.03 for SF66. In most cases glasses with higher densities also have higher refractive indices (e.g. SF type glasses). The density is mainly determined by the chemical composition of the glass. To a small amount the density is influenced by the annealing conditions of the glass near the transformation temperature. Due to the thermal ex...

Multilayer sputtering of SmFe/C(Al) plus appropriate thermal processing has been used to fabricate SmFeC thin films with A1 substitution for Fe. It was found that the SmFeAlC thin films exhibited exceptionally high Coercivities. A coercivity of 28 kOe was realized for the thin film with structure of Ta( l000~) / lSmFe(40~~/ G(Al)(5,&)]~50/Ta(200@ with subsequent annealing at 650°C.

Describes adaptation of simulated annealing to solve short playfair ciphers (80–120 letters) without using a probable word.

We used the so-called deterministic annealing algorithm due to Rose and Gurewitz by the classification of patent documents. A C++ program based on this algorithm was run first on some artificially constructed data and the results were good. Then we tested it on data sets obtained from some already classified patents. The conclusion we reached is that this algorithm provides an alternative class...
