This study connects quantum spin models to asexual evolution, finding parallel mutation-selection schemes accelerate model dynamics compared to Eigen models. This approach offers faster relaxation and broader applicability to various fitness functions.

Area of Science:

  • Theoretical Physics
  • Computational Biology
  • Evolutionary Dynamics

Background:

  • Asexual biological evolution models with single-peak fitness functions are often studied using mutation-selection schemes.
  • Quantum spin models provide a framework for understanding complex systems with interacting components.

Purpose of the Study:

  • To exactly solve the static and dynamic properties of an asexual evolution model.
  • To investigate the relationship between quantum spin models and biological evolution.
  • To compare the efficiency of parallel mutation-selection schemes with connected schemes.

Main Methods:

  • Establishing a connection between a quantum spin model and an asexual biological evolution model.
  • Applying a parallel mutation-selection scheme with a single-peak fitness function.

  • Exact analytical solutions for both static and dynamic aspects of the evolution model.

    • Main Results:

    • The study successfully solved both static and dynamic properties of the evolution model.
    • Relaxation in the parallel mutation-selection scheme was found to be faster than in the connected scheme of the Eigen model.
    • The developed method demonstrates potential for extension to other fitness functions.

    Conclusions:

    • The parallel mutation-selection scheme offers a more efficient approach for modeling asexual evolution compared to connected schemes.
    • The established link between quantum spin models and biological evolution provides new insights into evolutionary dynamics.
    • The methodology is adaptable and can be applied to a wider range of evolutionary models and fitness landscapes.
