General algorithm and sensitivity analysis for variational inequalities

open access: yesInternational Journal of Stochastic Analysis, Volume 5, Issue 1, Page 29-41, 1992., 1991
The fixed point technique is used to prove the existence of a solution for a class of variational inequalities related to odd order boundary value problems, and to suggest a general algorithm. We also study the sensitivity analysis for these variational inequalities and complementarity problems using the projection technique.

Iterative methods for nonlinear quasi complementarity problems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 10, Issue 2, Page 339-344, 1987., 1986
In this paper, we consider and study an iterative algorithm for finding the approximate solution of the nonlinear quasi complementarity problem of finding u ϵ k(u) such that where m is a point‐to‐point mapping, T is a (nonlinear) continuous mapping from a real Hilbert space H into itself and k*(u) is the polar cone of the convex cone k(u) in H. We also

Nonsmooth spectral gradient methods for unconstrained optimization

open access: yesEURO Journal on Computational Optimization, 2017
To solve nonsmooth unconstrained minimization problems, we combine the spectral choice of step length with two well-established subdifferential-type schemes: the gradient sampling method and the simplex gradient method.

An existence theorem for optimal control with nonstandard cost functionals

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 10, Issue 3, Page 609-611, 1987., 1987
An existence theorem for optimal control is obtained for a general nonstandard cost functional of fractional type in this work. As an application of our result we can derive an existence theorem for optimal control given by M. B. Subrahamanyam for a cost functional, which is a ratio of two given integral cost functionals.

On solving the plateau problem in parametric form

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 6, Issue 2, Page 341-361, 1983., 1981
This paper presents a numerical method for finding the solution of Plateau′s problem in parametric form. Using the properties of minimal surfaces we succeded in transferring the problem of finding the minimal surface to a problem of minimizing a functional over a class of scalar functions.

Testing reliability and validity of practitioner‐rated parental sensitivity: A novel tool for practice

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 45, Issue 2, Page 234-246, March 2024.
Abstract Improving parental sensitivity is an important objective of interventions to support families. This study examined reliability and validity of parental sensitivity ratings using a novel package of an e‐learning tool and an interactive decision tree provided through a mobile application, called the OK! package.

A new distributionally robust reward-risk model for portfolio optimization

open access: yesOpen Mathematics
A new distributionally robust ratio optimization model is proposed under the known first and second moments of the uncertain distributions. In this article, both standard deviation (SD) and conditional value-at-risk (CVaR) are used to measure the risk ...
