About

The workshop WEPO 2021 is intended to foster the discussion about Evolutionary Computation (EC) and Population-based Optimization (PO). Nature-inspired algorithms are largely used for solving optimization problems in a large number of fields due to their simplicity and effectiveness. The underlying principles behind these algorithms are simple enough to allow a great adaptability to various problems and domains and, while maintaining excellent effectiveness, they offer the possibility of obtaining explainable solutions. In a scenario where AI is increasingly predominant, but often with black box solutions, the explainability of EC and PO solutions may be an answer to the growing demand for understandable AI. The goal of this workshop is to explore and discuss the latest trends, promising results and hot topics in the fields of EC and PO, offering a discussion forum where new research collaborations can be established.

The workshop is directed towards researchers, practitioners, and students that work on or are interested in evolutionary computation (EC) and population-based optimization (PO) methods. Particular emphasis is given to recent advances in the use of EC and PO in the area of explainable AI.

Topics of Interest

The topics of the workshops include all the evolutionary computation methods and population-based optimization techniques, including, but not limited to:

  • Genetic Algorithms
  • Genetic Programming (tree-based, cartesian, graph-based, grammar-based, linear, semantic, and other kinds of GP)
  • Evolution Strategies
  • Differential Evolution
  • Particle Swarm Optimization and other swarm intelligence methods
  • Neuroevolution
  • Evolutionary robotics
  • Distributed methods in EC and swarm intelligence
  • Cooperative and competitive evolution
  • Fitness landscape analysis
  • Real-world applications
  • Software packages for EC and PO methods (including implementations for HPC and GPU)

Both theoretical works, novel techniques, and application to real-world problems are on-topic for the workshop. A particular focus of this workshop is the relation between these methods and the larger area of AI, in particular how they can contribute to the development of an explainable AI and how they can be hybridized with other machine learning methods.

Submissions

WEPO 2021 welcomes three different kinds of submissions:

  • Research Papers (up to 12 pages). Original and unpublished research works. The aim of this kind of papers it to disseminate to the community a complete research work.
  • Exploratory papers (up to 6 pages). Shorter papers with preliminary results or in-progress works. The authors are encouraged to present the main open problems and novel ideas to allow a fruitful discussion that can help in improving the work. Exploratory papers are a useful tool especially for students to start presenting their current research.
  • Proposal for software demos (2 pages short description). With a software demo, we want to encourage researchers to present their software, possibly helping other people in learning how to use it in their research. Authors are also encouraged to make a software repository available before the workshop, with the code and examples used in the demo.

All submissions must be formatted according to Springer’s LNCS style, and must be submitted using the EasyChair submission system by selecting the WEPO track.

Important dates (AoE)

Paper submission deadline: OCT 1, 2021 Oct 8, 2021

Notification to authors: Nov 8, 2021

Camera-ready submission: Nov 22, 2021

The workshop will be held online, with a program expected to run for one day, before the main conference. The exact date will be announced later. For further information about participation, please refer to the AIxIA 2021 website.

Publication

All accepted research and exploratory papers will be available in a local proceedings volume or, subject to confirmation, to CEUR-WS proceedings. All accepted software demos will be available in the local proceedings.

Authors of a selection of accepted papers will be invited to submit an extended and revised version for publication in an international journal (to be confirmed).
