This study presents a hybrid neural network and Gravitational Search Algorithm (HNGSA) method to solve well known Wessinger's equation. To aim this purpose, gravitational search algorithm (GSA) technique is applied to train a multi-layer perceptron neural network, which is used as approximation solution of the Wessinger's equation. A trial solution of the differential equation is written as sum...

This paper presents an effective optimization method for nonlinear constrained optimization of retaining structures. A newly developed heuristic global optimization algorithm called gravitational search algorithm (GSA) is introduced and applied for the optimization of retaining structures. The optimization procedure controls all geotechnical and structural design constraints while reducing the ...

The efficient use of electrical energy is a topic that has attracted attention for its environmental consequences. On the other hand, induction motors represent the main component in most industries. They consume the highest energy percentages in industrial facilities. This energy consumption depends on the operation conditions of the induction motor imposed by its internal parameters. Since th...

This paper proposes an effective memetic Gravitational Search Algorithm (GSA) that utilizes Solis and Wets’ (SW) algorithm as local search. GSA has good exploration ability and SW helps to improve the exploitation ability of the memetic algorithm. Furthermore, a selection strategy is proposed to select suitable individuals for local refinement that is based on subtractive clustering. Proposed m...

The problem to search for possible correlation between the Gamma Ray Bursts of still unknown origin and data recorded with the Gravitational Wave detectors is studied. A new algorithm for this search based on the Kolmogoroff comparison of distributions is given, which is not affected by the presence of non-gaussian noise.
