A Hybrid Gradient-Projection Algorithm for Averaged Mappings in Hilbert Spaces

open access: yesJournal of Applied Mathematics, 2012
It is well known that the gradient-projection algorithm (GPA) is very useful in solving constrained convex minimization problems. In this paper, we combine a general iterative method with the gradient-projection algorithm to propose a hybrid gradient ...

Non-Convex Split Feasibility Problems: Models, Algorithms and Theory

open access: yesOpen Journal of Mathematical Optimization, 2020
In this paper, we propose a catalog of iterative methods for solving the Split Feasibility Problem in the non-convex setting. We study four different optimization formulations of the problem, where each model has advantages in different settings of the ...

Strong Convergence of Modified Algorithms Based on the Regularization for the Constrained Convex Minimization Problem

open access: yesAbstract and Applied Analysis, 2014
As is known, the regularization method plays an important role in solving constrained convex minimization problems. Based on the idea of regularization, implicit and explicit iterative algorithms are proposed in this paper and the sequences generated by ...

OPTIMASS: A Package for the Minimization of Kinematic Mass Functions with Constraints [PDF]

open access: yes, 2015
Reconstructed mass variables, such as $M_2$, $M_{2C}$, $M_T^\star$, and $M_{T2}^W$, play an essential role in searches for new physics at hadron colliders.

Minimal curvature-constrained networks [PDF]

open access: yesJournal of Global Optimization, 2018
This paper introduces an exact algorithm for the construction of a shortest curvature-constrained network interconnecting a given set of directed points in the plane and an iterative method for doing so in 3D space. Such a network will be referred to as a minimum Dubins network, since its edges are Dubins paths (or slight variants thereof). The problem

Constrained Texture Synthesis via Energy Minimization [PDF]

open access: yesIEEE Transactions on Visualization and Computer Graphics, 2007
This paper describes CMS (constrained minimization synthesis), a fast, robust texture synthesis algorithm that creates output textures while satisfying constraints. We show that constrained texture synthesis can be posed in a principled way as an energy minimization problem that requires balancing two measures of quality: constraint satisfaction and ...

Muscle-Effort-Minimization-Inspired Kinematic Redundancy Resolution for Replicating Natural Posture of Human Arm

open access: yesIEEE Transactions on Neural Systems and Rehabilitation Engineering, 2022
Replicating natural postures of human arms is essential to generate human-like behaviors in robotic applications for humans nearby. However, how to realize this requirement in interactive scenarios remains a challenge due to the kinematic redundancy and ...

Large volume minimizers of a non local isoperimetric problem: theoretical and numerical approaches [PDF]

open access: yes, 2018
We consider the volume-constrained minimization of the sum of the perimeter and the Riesz potential. We add an external potential of the form $\|x\|^{\beta}$ that provides the existence of a minimizer for any volume constraint, and we study the geometry ...
