This study introduces a novel artificial chemistry using directed graphs, bridging computation and chemistry. This reflexive system allows graphs to interact with their own structure, generating complex and diverse outcomes.

Area of Science:

  • Theoretical Computer Science
  • Computational Chemistry
  • Artificial Life

Background:

  • A conceptual divide exists between formal computation systems and abstract chemistry models.
  • Existing models often separate the machine (e.g., finite-state machine) from its input.
  • This separation limits the potential for emergent complexity in artificial chemistries.

Purpose of the Study:

  • To bridge the divide between computation and chemistry.
  • To propose a novel formalism for constructive artificial chemistry.
  • To explore the implications of reflexivity in chemical modeling.

Main Methods:

  • Developed a formalism based on directed graph structures.
  • Adapted concepts from finite-state machine theory.

Related Experiment Videos

  • Implemented a reflexive construction process where graphs interact with their own topology.

    • Main Results:

    • Demonstrated continuous emergence of complex, self-similar topologies.
    • Observed novel reaction pathways and open-ended diversity.
    • Highlighted the significance of reflexivity for generating complex systems.

    Conclusions:

    • The proposed reflexive artificial chemistry effectively bridges computation and chemistry.
    • Reflexivity is a crucial missing element in prior model chemistries.
    • The formalism supports the generation of complex, diverse, and self-organizing structures.
