Choice Function-Based Hyper-Heuristics for Causal Discovery under Linear Structural Equation Models [PDF]

open access: yesBiomimetics
Causal discovery is central to human cognition, and learning directed acyclic graphs (DAGs) is its foundation. Recently, many nature-inspired meta-heuristic optimization algorithms have been proposed to serve as the basis for DAG learning.

Student Surpasses the Teacher: Apprenticeship Learning for Quadratic Unconstrained Binary Optimisation

open access: yesAlgorithms
This study introduces a novel train-and-test approach referred to as apprenticeship learning (AL) for generating selection hyper-heuristics to solve the Quadratic Unconstrained Binary Optimisation (QUBO) problem.

Hyper-heuristics for grouping problems. [PDF]

open access: yes, 2015
Grouping problems are hard to solve combinatorial optimization problems which require partitioning of objects into a minimum number of subsets while another additional objective is simultaneously optimized. Considerable research e ort has recently been directed towards automated problem-independent reusable heuristic search methodologies such as hyper ...

A Feature-Independent Hyper-Heuristic Approach for Solving the Knapsack Problem

open access: yesApplied Sciences, 2021
Recent years have witnessed a growing interest in automatic learning mechanisms and applications. The concept of hyper-heuristics, algorithms that either select among existing algorithms or generate new ones, holds high relevance in this matter.

Assessing hyper-heuristic performance [PDF]

open access: yesJournal of the Operational Research Society, 2020
Limited attention has been paid to assessing the generality performance of hyper-heuristics. The performance of hyper-heuristics has been predominately assessed in terms of optimality which is not ideal as the aim of hyper-heuristics is not to be competitive with state of the art approaches but rather to raise the level of generality, i.e.

Hyper-Heuristics [PDF]

open access: yesProceedings of the Companion Publication of the 2015 Annual Conference on Genetic and Evolutionary Computation, 2015
Practitioners often need to solve real world problems for which no custom search algorithms exist. In these cases they tend to use general-purpose solvers that have no guarantee to perform well on their specific problem. The relatively new field of hyper-heuristics provides an alternative to the potential pit-falls of general-purpose solvers, by ...

Identifying Hyper-Heuristic Trends through a Text Mining Approach on the Current Literature

open access: yesApplied Sciences, 2022
Hyper-heuristics have arisen as methods that increase the generality of existing solvers. They have proven helpful for dealing with complex problems, particularly those related to combinatorial optimization.
