A Hyperheuristic Approach for Unsupervised Land-Cover Classification [PDF]

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2016
Unsupervised land-use/cover classification is of great interest, since it becomes even more difficult to obtain high-quality labeled data. Still considered one of the most used clustering techniques, the well-known $k$ -means plays an important role in the pattern recognition community.

Investment Opportunities Forecasting: Extending the Grammar of a GP-based Tool [PDF]

open access: yes, 2012
In this paper we present a new version of a GP financial forecasting tool, called EDDIE 8. The novelty of this version is that it allows the GP to search in the space of indicators, instead of using pre-specified ones.

A Hyperheuristic Approach to Scheduling a Sales Summit [PDF]

open access: yes, 2001
The concept of a hyperheuristic is introduced as an approach that operates at a higher lever of abstraction than current metaheuristic approaches. The hyperheuristic manages the choice of which lower-level heuristic method should be applied at any given time, depending upon the characteristics of the region of the solution space currently under ...

Solving high school timetabling problems worldwide using selection hyper-heuristics [PDF]

open access: yes, 2015
High school timetabling is one of those recurring NP-hard real-world combinatorial optimisation problems that has to be dealt with by many educational institutions periodically, and so has been of interest to practitioners and researchers. Solving a high

Ensemble move acceptance in selection hyper-heuristics [PDF]

open access: yes, 2016
Selection hyper-heuristics are high level search methodologies which control a set of low level heuristics while solving a given problem. Move acceptance is a crucial component of selection hyper-heuristics, deciding whether to accept or reject a new ...

A case study of controlling crossover in a selection hyper-heuristic framework using the multidimensional knapsack problem [PDF]

open access: yes, 2015
Hyper-heuristics are high-level methodologies for solving complex problems that operate on a search space of heuristics. In a selection hyper-heuristic framework, a heuristic is chosen from an existing set of low-level heuristics and applied to the ...

Evolvability Metric Estimation by a Parallel Perceptron for On-Line Selection Hyper-Heuristics

open access: yesIEEE Access, 2017
Online hyper-heuristic selection is a novel and powerful approach to solving complex problems. This approach dynamically selects, based on the state of a given solution, the most promising operator (from a pool of operators) to continue the search ...
