CEC30 – Special Session on candidate solutions representation and fitness landscape manipulation

This WCCI 2020 special session is organized in association with the IEEE Computational Intelligence Society’s Technical Committee on Bioinformatics and Bioengineering (BBTC).

Aim

In global optimization techniques, it is often the case that the data structures used to represent a candidate solution can be directly decoded and interpreted; hence, the best fitting individual immediately provides an explicit and human-readable description of the optimal solution. Research mainly focused on the creation of novel strategies, aimed at balancing the exploration and exploitation capabilities of optimization algorithms.

Although this well established research line is very prolific—paving the way to the design of efficient algorithms even for large-scale problems—there is another promising direction that could be investigated, consisting in the modification of the search space, that is, space transformation able to dilate, shrink, stretch, collapse, or remap the fitness landscape, leading to alternative or simplified formulations of the original optimization problem.

In discrete domains, a similar approach can be performed by embedding implicit or explicit assumptions into the structure of candidate solutions, so that genetic operators can explore the feasible search space in a “smarter” way, reducing the overall computational effort.  Example of this technique include generative representations, techniques based on grammars, single parent techniques where example genes are incorporated, and other structured representations that starkly limit the portion of the search domain examined. 

This special session aims at gathering the researchers who are investigating new directions and ideas in the field of candidate solutions representation and its dual notion fitness landscape manipulation.

Scope

This Special Session welcomes any paper considering all kinds of non-conventional candidate solutions representation, including the dual perspective of fitness landscape manipulation.

Examples include but are not limited to:

  • Non-conventional representations of candidate solutions
  • Dilation functions and other functions that reshape the fitness landscape
  • Alternative semantics for candidate solutions
  • Fitness landscape modification, simplification, and restriction
  • Novel closed variation/evolutionary operators
  • Implicit/relative representations
  • Generative or developmental representations
  • Self-adaptive representations
  • Parameterized manifolds of representations
  • State-conditioned representations
  • Procedural representations
  • Generative automata
  • Surrogate models
