Workshop on Landscape-Aware Heuristic Search

17 September 2016, Edinburgh, UK

Held in conjunction with the 14th International Conference on
Parallel Problem Solving from Nature (PPSN 2016)

Overview

Fitness landscape analysis and visualisation can provide significant insights into problem instances and algorithm behaviour. The aim of the workshop is to encourage and promote the use of landscape analysis to improve search algorithms and their understanding. Examples include landscape analysis as a tool to inform the design of algorithms, landscape metrics for online adaptation of search strategies, mining landscape information to predict instance hardness and algorithm runtime. The workshop seeks to bring together researchers interested in landscape analysis and in exploiting problem structure to develop informed search strategies. The workshop provides a unique opportunity to present existing work, propose new ideas or put forward position statements.
Relevant topics include, but are not limited to:

  • Evolvability and searchability characterisation
  • Exploiting problem structure
  • Exploratory landscape analysis
  • Fitness landscape analysis
  • Fitness landscape visualisation
  • Fitness landscape theory
  • Grey-box optimisation
  • Informed search strategies
  • Local optima networks
  • Multi-objective fitness landscapes
  • Performance and failure prediction
