On q-Quasi-Newton’s Method for Unconstrained Multiobjective Optimization Problems
Mathematics, 2020 A parameter-free optimization technique is applied in Quasi-Newton’s method for solving unconstrained multiobjective optimization problems. The components of the Hessian matrix are constructed using q-derivative, which is positive definite at every ...

Classification of the Types of Defects in Steam Generator Tubes using the Quasi-Newton Method [PDF]
Journal of Electrical Engineering and Technology, 2010 Multi-layer perceptron neural networks have been constructed to classify four types of defects in steam generator tubes. Three features are extracted from the signals of the eddy current testing method. These include maximum impedance, phase angle at the point of maximum impedance, and an angle between the point of maximum impedance and the point of ...

On the construction of minimisation methods of quasi-Newton type
Journal of Computational and Applied Mathematics, 1987 The paper investigates possibilities for the formulation of new quasi- Newton type methods. In doing so the so-called secant equation of the classical quasi-Newton algorithms is replaced by a more general equation. In this way it is possible to give a nonlinear approximation of the Newton equation, the solution of which corresponds to the Newton search

An Approximate Quasi-Newton Bundle-Type Method for Nonsmooth Optimization
Abstract and Applied Analysis, 2013 An implementable algorithm for solving a nonsmooth convex optimization problem is proposed by combining Moreau-Yosida regularization and bundle and quasi-Newton ideas. In contrast with quasi-Newton bundle methods of Mifflin et al. (1998), we only assume that the values of the objective function and its subgradients are evaluated approximately, which ...
