A unified hyper-heuristic framework for solving bin packing problems

open access: yes, 2014
One- and two-dimensional packing and cutting problems occur in many commercial contexts, and it is often important to be able to get good-quality solutions quickly.

The winner doesn't need to take it all: Unravelling the gendered value of work time

open access: yesInternational Journal of Management Reviews, EarlyView.
Abstract How people understand, negotiate and use time at work shapes their daily experiences. Yet, when work time is divided, allocated and valued in workplaces, women often lose out. Despite pervasive empirical evidence of gender gaps, research has largely overlooked the deeper role of time in shaping inequality.

A unified formulation for home healthcare routing and scheduling problems

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract Home Healthcare is an essential component of healthcare systems, where caregivers visit patients' homes to deliver services. While presenting advantages with respect to institutional care, such as being cost‐effective and alleviating family burdens, it presents challenges in scheduling and routing caregivers efficiently.

Deep reinforcement learning for multi‐restart metaheuristics: an environment design for a hybrid of unbiased exploratory search and covariance matrix adaptation evolution strategy

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract Multi‐restart metaheuristics can be highly effective for complex optimization problems, yet their performance depends critically on how restarts and algorithmic parameters are selected. This paper introduces a reinforcement learning approach for managing restart‐level decisions and parameter configurations in the UES–CMA‐ES hybrid ...

The Collective Action of Firms on Regulatory Science: Mechanistic Toxicology as a Market‐Making Epistemic Strategy in the R&D Agrochemical Industry

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT The influence of agrochemical firms on testing and risk assessment standards constitutes a central yet understudied dimension of the political economy of agrochemicals and the formation of a corporate‐dominated global pesticide regime. How leading R&D firms—formally positioned as competitors—have converged in the production and dissemination ...

Hyper-heuristic based local search for combinatorial optimisation problems

open access: yes, 2018
Combinatorial optimisation is often needed for solving real-world problems, which are often NP-hard so exact methods are not suitable. Instead local search methods are often effective to find near-optimal solutions quickly.
