Four Recent Research Topics on Numerical and Spiking Neural P Systems
Two research directions on numerical P systems and two on spiking neural P systems which were recently explored are shortly discussed. They deal with very natural versions of these classes of P systems which were not investigated before. Besides definitions, one recalls a few of the results obtained about these new classes of P systems and one points out open problems and directions for further...

متن کاملTHIN WALLED STEEL SECTIONS’ FREE SHAPE OPTIMIZATION USING CHARGED SYSTEM SEARCH ALGORITHM
Graph theory based methods are powerful means for representing structural systems so that their geometry and topology can be understood clearly. The combination of graph theory based methods and some metaheuristics can offer effective solutions for complex engineering optimization problems. This paper presents a Charged System Search (CSS) algorithm for the free shape optimizations of thin-wall...

متن کاملSymplectic and symmetric methods for the numerical solution of some mathematical models of celestial objects
In the last years, the theory of numerical methods for system of non-stiff and stiff ordinary differential equations has reached a certain maturity. So, there are many excellent codes which are based on Runge–Kutta methods, linear multistep methods, Obreshkov methods, hybrid methods or general linear methods. Although these methods have good accuracy and desirable stability properties such as A...
