    TECHNICAL INTRODUCTION
    A Class of Models with the Potential to Represent Fundamental Physics
    BY STEPHEN WOLFRAM
    A class of models intended to be as minimal and structureless as possible is introduced.
    The models can be viewed as describing networks, relations, sets, or a variety of other structures.
    Even in cases with simple rules, highly complex behavior can emerge, some of which has striking similarities to known core features of fundamental physics.
