6th Workshop on Landscape-Aware Heuristic Search (LAHS)
Held in conjunction with the Genetic and Evolutionary Computation Conference (GECCO 2023)
Lisbon, Portugal, July 15th-19th 2023
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 the understanding, the design and, eventually, the performance of search algorithms. 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 will focus on, but not be limited to, topics such as:
Visualisations
Local optima networks
Exploiting problem structure
Hyperparameter optimisation
Feature selection search spaces
Informed search strategies
Neural architecture search spaces
Multi-objective fitness landscapes
Performance and failure prediction
Neural network loss landscape analysis
Landscape metrics for automated algorithm selection
Proposal of new fitness landscape features
Real-world applications of fitness landscape analysis
