Abstract
In this study, the solution of the fuzzy nonlinear optimization problems is achieved by a recurrent neural network model. Since there are a few researches for solving fuzzy optimization problems by neural networks, we introduce a new model with reduced complexity to solve the problem. By reformulating the original program to an interval problem and then a weighting problem, the Karush–Kuhn–Tucker optimality conditions are stated. Moreover, we employ the optimality conditions into a neural network as a basic tool to solve the problem. Besides, the global convergence and the Lyapunov stability analysis of the system are debated in this study. Finally, different numerical examples allow to validate our algorithm with the proposed neural network compared to some other alternative networks.
期刊介绍:
The Journal of Computational and Applied Mathematics publishes original papers of high scientific value in all areas of computational and applied mathematics. The main interest of the Journal is in papers that describe and analyze new computational techniques for solving scientific or engineering problems. Also the improved analysis, including the effectiveness and applicability, of existing methods and algorithms is of importance. The computational efficiency (e.g. the convergence, stability, accuracy, ...) should be proved and illustrated by nontrivial numerical examples. Papers describing only variants of existing methods, without adding significant new computational properties are not of interest.
The audience consists of: applied mathematicians, numerical analysts, computational scientists and engineers.
