Pattern Search Methods for Linearly Constrained Minimization [PDF]
The given paper is a continuation of the preceding paper [see SIAM J. Optim. 9, 1082--1099 (1999; Zbl 1031.90047)]. The authors develop a general class of feasible point pattern search algorithms for optimization problems with linear constraints of the form \[ \begin{aligned} \text{minimize }\quad & f(x)\\ \text{subject to }\quad & 1\leq Ax\leq u\end ...

ABSTRACT Objective To explore how cerebral hypoxia and Normal‐Appearing White Matter (NAWM) integrity affect MS lesion burden and clinical course. Methods Seventy‐nine MS patients, including 13 clinically isolated syndrome (CIS) patients and 66 relapsing–remitting multiple sclerosis (RRMS) patients, and 44 healthy controls (HCs) were recruited from ...

A New Nonconvex Sparse Recovery Method for Compressive Sensing
As an extension of the widely used ℓr-minimization with 0 < r ≤ 1, a new non-convex weighted ℓr − ℓ1 minimization method is proposed for compressive sensing.

The Constrained Crossing Minimization Problem [PDF]
In this paper we consider the constrained crossing minimization problem defined as follows. Given a connected planar graph G = (V,E), a combinatorial embedding II(G) of G, and a set of pairwise distinct edges F ⊆ V × V, find a drawing of G′ = (V,E ∼ F) such that the combinatorial embedding II(G) of G is preserved and the number of edge crossings is ...

Docking sites inside Cas9 for adenine base editing diversification and RNA off-target elimination
Current SpCas9 adenine base editors that minimise RNA off-target activities have constrained editing windows. Here the authors use domain insertion of TadA into Cas9 to narrow, expand or shift the editing window with RNA off-target minimization ...

Constrained Minimization Problem for Image Restoration Based on Non-Convex Hybrid Regularization
It is widely known that the classic total variation(TV) model has been proven to be very effective in preserving sharp edges. However, the TV model suffers from the staircase effects which produce blocking artifacts in the restored images. In this paper,

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Relaxed Viscosity Approximation Methods with Regularization for Constrained Minimization Problems
We introduce a new relaxed viscosity approximation method with regularization and prove the strong convergence of the method to a common fixed point of finitely many nonexpansive mappings and a strict pseudocontraction that also solves a convex ...

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control
This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...
