This study explores self-organized modularization in evolutionary computation, finding that effective modularity can drive solution modularization. This highlights the role of schemata as building blocks in genetic algorithms.

Area of Science:

  • Computer Science
  • Artificial Intelligence
  • Evolutionary Computation

Background:

  • Modularization is a key principle in technical applications, especially software engineering.
  • The study investigates if evolutionary computation mechanisms inherently lead to solution modularization.
  • Focus is on modularization arising solely from standard evolutionary operators (selection, recombination, mutation).

Purpose of the Study:

  • To determine if evolutionary computation processes can lead to self-organized modularization.
  • To introduce quantitative measures for modularity: Built-in Modularity and Effective Modularity.
  • To analyze the role of Effective Modularity as a selection factor.

Main Methods:

  • Combining formalizations by Radcliffe and Altenberg.

  • Developing quantitative measures for Built-in and Effective Modularity.
  • Theoretical analysis and simulations using a minimalist toy model.

    • Main Results:

    • Effective Modularity can act as a selection factor under specific conditions, promoting self-organized modularization.
    • Experimental results underscore the significance of Effective Modularity over Built-in Modularity.
    • A complex self-amplification of highly modular equivalence classes was observed.

    Conclusions:

    • Self-organized modularization is achievable in evolutionary computation through inherent operators.
    • Effective Modularity plays a crucial role in driving this process.
    • Findings have implications for existing and future evolutionary computation models, emphasizing schemata as building blocks.
