Furthermore, the complementary aspects of the structure and behavior of genetic algorithm and simulated annealing are used to combine the mechanisms and operators to develop a class of global hybrid strategy with parallel searching and probabilistic jumping abilities.

The limiting characteristics of the laser (optimum structure parameters, minimum threshold current density, and characteristic temperature of the optimized structure) are discussed at length.

A maximum CW output power of 4.4 W is reached in an optimized structure.

In order to study the electronic transport properties, an optimized structure in which there is no parallel conduction over the doped layer was chosen.

The final optimized structure of melittin strongly depends on the temperature.

ZnO thin film annealed at 400°C in N2 for 2 h exhibited the optimal structure and PL property, and the grain size and the lattice constants of the film were calculated (41.6 nm, a = 3.253 ? and c = 5.210 ?).

Formulation of the problem of designing the optimal structure of an active system was considered within the framework of the game-theoretical model of interaction of its participants.

The problem of designing the optimal structure of an organization was considered as that of determining a graph with the minimum cost of a group of executives realizing the given functions.

The notion of ideally coordinated collection of functions for which determination of the optimal structure is substantially simpler was introduced.

Optimality conditions of a flexural member with lower bound on its cross section have been discussed by prager and Morz. The optimal design of fibre-reinforced plates having prescribed minimum specific fibre-volume has been obtained by Charrett and Rozvany.But the plastic speciality of optimal members at its minimum section was neglectd in their discussion so that optimality conditions might be inadequate.

As a matter of fact it is very difficult and unnecessary as well to findout the strict soluttions to the problems,which have arisen in the optimum designof structures in engineering science.What is required of us is to find out the po-ssible approximation of optimum design based on the initial structures,according tothe features of structure forms and the requirements for property specifications.On the basis of the above-mentioned idea,in line with characters of trussstructure optimum approximation of design...

In this paper the hierarchical optimization of a nonlinear dynamical input-output model with time delays is studied. Combinig the strategies of costate prediction approach by Hassan and Singh and the time-delay coordination algorithm by Tamura, the variable prediction-time decomposition technique is put forward. Using the technique, the nonlinear three-level hierarchical optimization structure is formulated. The related conclusions proposed by the paper may also be used to solve other high dimensional nonlinear...
