To perform a quantitative simulation using the Phase Field Method (PFM) in a real alloy system, a new strategy of modeling the microstructure evolution of Ni-base superalloy is proposed in the present paper. In this strategy, the Calculation Phase Diagram (CALPHAD) method and Cluster Variation Method (CVM) are combined with the PFM, in which the four sub-lattice model is used to evaluate the fr...

Natural deduction is essentially a sequential decision task, similar to many game-playing tasks. Such a task is well suited to benefit from the techniques of neuro-evolution. Symbiotic, Adaptive Neuro-Evolution (SANE)(Moriarty and Miikkulainen 1996) has proven successful at evolving networks for such tasks. This paper will show that SANE can be used to evolve a natural deduction system on a neu...

Evolution strategies are inspired in biology and form part of a larger research field known as evolutionary algorithms. Those strategies perform a random search in the space of admissible functions, aiming to optimize some given objective function. We show that simple evolution strategies are a useful tool in optimal control, permitting one to obtain, in an efficient way, good approximations to...

This paper puts forward two useful methods for self-adaptation of the mutation distribution - the concepts of derandomization and cumulation. Principle shortcomings of the concept of mutative strategy parameter control and two levels of derandomization are reviewed. Basic demands on the self-adaptation of arbitrary (normal) mutation distributions are developed. Applying arbitrary, normal mutati...

This paper provides an overview on obtaining low-carbon ultra-fine grained dual-phase steels through rapid intercritical annealing of cold-rolled sheet as improved materials for automotive applications. A laboratory processing route was designed that involves cold-rolling of a tempered martensite structure followed by a second tempering step to produce a fine grained aggregate of ferrite and ca...

The session will focus on the recent developments in the theory of nonlinear evolution equations, optimal control theory and related topics including real life problems of mechanics, biology, economics, and medicine. The main topics of the session include, but are not limited to, analysis of solutions of evolution problems and partial differential equations, operator inclusions, evolution inclu...

The intention of this work is to eliminate the need for a synchronous generation scheme in the (μ +, λ) evolution strategy. It is motivated by the need for a more practical implementation of selection strategies on parallel machine architectures. This strategy is known as continuous or steady state selection. Continuous selection is known to reduce significantly the number of function evaluatio...

the development of regional logistics system is a typical self-adapting and self-organizing evolution process. According to the structures and operation of regional logistics, the self-organizing characteristics of regional logistics synergetic evolution are analyzed. Moreover, the space evolution phases of regional logistics system are educed based on the complex system theory, and the enterpr...
