Multiway Turing Machines: A 2021 Theoretical Model

The article revisits the concept of multiway Turing machines, a theoretical model from 2021 that extends classical Turing machines with multiple possible transitions at each step. It explores how this model can represent nondeterministic and parallel computation, offering insights into the foundations of computing before the rise of modern AI. While not immediately practical, this concept helps researchers understand computational complexity and the limits of deterministic algorithms.
