A new steplength selection for scaled gradient methods with application to image deblurring [PDF]
, 2015 Gradient methods are frequently used in large scale image deblurring problems since they avoid the onerous computation of the Hessian matrix of the objective function.

International Journal of Mathematics and Mathematical Sciences, 1999 In this paper, a hyperbolic differential inclusion with nonmonotone discontinuous and nonlinear term, which the generalized velocity acts as its variable, is studied and the existence and decay of its weak solution are obtained.

Practical implementation of an interior point nonmonotone line search filter method [PDF]
, 2008 Versão não definitiva do artigoHere we present a primal-dual interior point nonmonotone line search filter method for nonlinear programming. The filter relies on three measures, the feasibility, the centrality and the optimality presented in the ...

Fractional elliptic obstacle systems with multivalued terms and nonlocal operators
Nonlinear AnalysisIn this paper, we introduce and study a fractional elliptic obstacle system, which is composed of two elliptic inclusions with fractional (pi, qi)-Laplace operators, nonlocal functions, and multivalued terms.

Nonmonotone hybrid tabu search for Inequalities and equalities: an experimental study [PDF]
, 2013 The main goal of this paper is to analyze the behavior of nonmonotone hybrid tabu search approaches when solving systems of nonlinear inequalities and equalities through the global optimization of an appropriate merit function.

Interpolation Theorems for Nonmonotonic Reasoning Systems [PDF]
, 2002 Craig's interpolation theorem (Craig 1957) is an important theorem known for propositional logic and first-order logic. It says that if a logical formula $ $ logically follows from a formula $ $, then there is a formula $ $, including only symbols that appear in both $ , $, such that $ $ logically follows from $ $ and $ $ logically follows from

Product Positioning and Incentives to Innovate
Journal of Economics &Management Strategy, EarlyView.ABSTRACT This paper shows that product positioning affects the incentives to invest in process innovation. The result is found using a model of price competition with three firms under horizontal product differentiation—and then extended to a more general Bertrand triopoly.

A nonmonotone trust-region-approach with nonmonotone adaptive radius for solving nonlinear systems
Iranian Journal of Numerical Analysis and Optimization, 2016 This paper presents a trust-region procedure for solving systems of nonlinear equations. The proposed approach takes advantages of an effective adaptive trust-region radius and a nonmonotone strategy by combining both of them appropriately. It is believed that selecting an appropriate adaptive radius based on a suitable nonmonotone strategy can improve
