This study optimized a string rewriting system to enhance self-replication. Higher replicative capacity in evolutionary systems leads to stronger connectivity and increased evolvability.

Area of Science:

  • Computational Biology
  • Artificial Life
  • Systems Evolution

Background:

  • Evolutionary systems require mechanisms for replication and adaptation.
  • String rewriting systems offer a model for studying evolutionary dynamics.

Purpose of the Study:

  • To optimize a string rewriting system for maximum 'replicative capacity'.
  • To investigate the relationship between replicative capacity and system evolvability.

Main Methods:

  • Experimental optimization of rewriting rules to maximize self-replication.
  • Analysis of connectivity between self-replicating strings using 'hyperblobs'.

Main Results:

  • An optimized rule set enabled widespread self-replication via a special copying character.

  • High replicative capacity correlated with strong connectivity among self-replicating genotypes.

    • Conclusions:

    • Maximizing replicative capacity is crucial for enhancing evolvability in artificial systems.
    • Connectivity of self-replicating elements directly impacts a system's evolutionary potential.
