The investigations in the paper have been carried out against the background of an integrated approach to the structural design problem. Due to the complex nature of the search space and the continous-discrete-binary system vector in the general case of structural optimization, conventional methods can not be used. Evolution strategies have shown their general capability to solve the sizing and...

Evolution Strategies are global, direct optimisation algorithms, which have proven their efficiency in engineering applications for a large number of industrial applications. In this paper, the basic algorithm and some of its recent variants for design optimisation are presented. In addition, we give an overview of applications and a comparison to other optimisation algorithms. As an example we...

Nanocomposite of titanium diboride/titanium carbide was fabricated by combustion synthesis of mechanically milled reactant powders. The stoichiometric mixture of Ti and B4C as starting materials milled for 1, 3, 6 and 9 h. Milled powders pressed to form pellets then green compacts were placed in a tube furnace that preheated to 1100 oC in inert atmosphere (Ar).The samples were investigated by X...

Natural evolution is a population-based optimization process. Simulating this process on a computer results in stochastic optimization techniques that can often outperform classical methods of optimization when applied to difficult real-world problems. There are currently three main avenues of research in simulated evolution: genetic algorithms, evolution strategies, and evolutionary programmin...
