Efficient heuristics for the workover rig routing problem with a heterogeneous fleet and a finite horizon

open access: yes, 2016
Onshore oil fields may contain hundreds of wells that use sophisticated and complex equipments. These equipments need regular maintenance to keep the wells at maximum productivity.

Fundamental Challenges, Physical Implementations, and Integration Strategies for Ising Machines in Large‐Scale Optimization Tasks

open access: yesAdvanced Electronic Materials, EarlyView.
Ising machines are emerging as specialized hardware solvers for computationally hard optimization problems. This review examines five major platforms—digital CMOS, analog CMOS, emerging devices, coherent optics, and quantum systems—highlighting physics‐rooted advantages and shared bottlenecks in scalability and connectivity.

Improved Heuristics for the Early/Tardy Scheduling Problem with No Idle Time [PDF]

open access: yes
In this paper we consider the single machine earliness/tardiness scheduling problem with no idle time. We present two new heuristics, a dispatch rule and a greedy procedure, and also consider the best of the existing dispatch rules.

Capacitive versus Faradaic Microelectrodes for Extracellular Stimulation: A Fully Coupled FEM–Hodgkin–Huxley Study of Thresholds and Current Redistribution

open access: yesAdvanced Electronic Materials, EarlyView.
A fully coupled FEM–HH model shows that ideally capacitive microelectrodes can achieve lower charge‐density thresholds than Faradaic contacts under current‐controlled stimulation. The advantage stems from the dynamics of surface current density on capacitive interfaces, which redirects current beneath adherent neurons.

Smart Exploration of Perovskite Photovoltaics: From AI Driven Discovery to Autonomous Laboratories

open access: yesAdvanced Energy Materials, EarlyView.
In this review, we summarize the fundamentals of AI in automated materials science, and review AI applications in perovskite solar cells. Then, we sum up recent progress in AI‐guided manufacturing optimization, and highlight AI‐driven high‐throughput and autonomous laboratories.

A meta-heuristic extension of the Lagrangian heuristic framework

open access: yesOptimization Methods and Software
Lagrangian heuristics for discrete optimization work by modifying Lagrangian relaxed solutions into feasible solutions to an original problem. They are designed to identify feasible, and hopefully also near-optimal, solutions and have proven to be highly successful in many applications.

Meta-heuristics for stable scheduling on a single machine. [PDF]

open access: yes
This paper presents a model for single-machine scheduling with stability objective and a common deadline. Job durations are uncertain, and our goal is to ensure that there is little deviation between planned and actual job starting times.

Coping with uncertainty in public health: the use of heuristics

open access: yes, 2014
The observation that experts and lay people use cognitive shortcuts or heuristics to arrive at judgements about complex problems is certainly not new.

Complex Iridium Oxides Converge In Structure And Reactivity During Acidic Oxygen Evolution Electrocatalysis

open access: yesAdvanced Energy Materials, EarlyView.
Ir‐based double perovskites restructure during acidic oxygen evolution electrocatalysis through dissolution of non‐Ir cations and convergence toward IrOx active‐site motifs with similar structure and intrinsic activity across compositions. The identity of the dissolving cations controls dissolution and surface reconstruction kinetics, clarifying how ...
