    Area of Science:

    • Complex Systems
    • Network Theory
    • Evolutionary Biology

    Background:

    • Underoccupied systems, characterized by large networks with sparse particle distribution, present unique challenges for modeling.
    • Stochastic processes are crucial for understanding the dynamics of such systems.

    Purpose of the Study:

    • To develop a graph-based stochastic description for underoccupied systems.
    • To analyze the impact of evolutionary processes, specifically mutation and selection, on these networks.

    Main Methods:

    • Utilized graph theory to represent the network structure.
    • Developed a stochastic model to simulate particle dynamics.
    • Incorporated mutation (component hopping) and selection as key evolutionary operators.

    Main Results:

    • The study provides a formal stochastic framework for analyzing underoccupied systems.
    • The model allows for the investigation of how mutation and selection shape network evolution.

    Conclusions:

    • The graph-based stochastic model offers a powerful tool for studying evolutionary dynamics in sparse networks.
    • This approach can be applied to various fields dealing with large, sparsely populated systems.
