Some Characterizations of General Preinvex Functions
International Journal of Analysis and Applications, 2017 In this paper, we consider a new class of general preinvex functions involving an arbitrary function. We show that the optimality condition for general preinvex functions on general invex set can be characterized by a class of variational-like inequality.

Invex functions and constrained local minima [PDF]
Bulletin of the Australian Mathematical Society, 1981 If a certain weakening of convexity holds for the objective and all constraint functions in a nonconvex constrained minimization problem, Hanson showed that the Kuhn-Tucker necessary conditions are sufficient for a minimum. This property is now generalized to a property, called K-invex, of a vector function in relation to a convex cone K.

Sumatriptan‐naproxen sodium in migraine: A review
European Journal of Neurology, Volume 31, Issue S2, September 2024.Abstract Background Varied responses to acute migraine medications have been observed, with over one‐third (34.5%) of patients reporting insufficient headache relief. Sumatriptan‐naproxen sodium, a single, fixed‐dose combination tablet comprising sumatriptan 85 mg and naproxen sodium 500 mg, was developed with the rationale of targeting multiple ...

On some connection between invex and convex problems in nonlinear programming [PDF]
, 2001 A method of solving problems involving invex functions via certain convex problems is presented. Nonsmooth problems are also considered. A definition of such a Fenchel-Young type duality for an invex function f that its second dual is equal to f is ...

Up and Down h-Pre-Invex Fuzzy-Number Valued Mappings and Some Certain Fuzzy Integral Inequalities
, 2022 The objective of the current paper is to incorporate the new class and concepts of convexity and Hermite–Hadamard inequality with the fuzzy Riemann integral operators because almost all classical single-valued and interval-valued convex functions ...

Input Invex Neural Network [PDF]
Connected decision boundaries are useful in several tasks like image segmentation, clustering, alpha-shape or defining a region in nD-space. However, the machine learning literature lacks methods for generating connected decision boundaries using neural ...

Journal of the International AIDS Society, Volume 27, Issue 6, June 2024.Abstract Introduction To achieve epidemic control of infectious diseases, engaging higher‐burden populations with accessible diagnostic services is critical. HIV self‐testing (HIVST) is a promising option. Methods We implemented an online HIVST programme for key populations across India. Eligible clients were 18 years or older, self‐reported a negative

Nonsmooth Invex Functions and Sufficient Optimality Conditions
Journal of Mathematical Analysis and Applications, 2001 The author unifies various definitions of non-smooth invex functions by introducing the \(K\)-directional derivative of a function in the following way. Let \(X\subset\mathbb{R}^n\) be an open set, \(f:X\to\mathbb{R}\), \(x\in X\) and \(K\) be a local cone approximation; the positive homogeneous function \(f^K(x,.): \mathbb{R}^n\to [-\infty,\infty ...
