Nondeterministic Turing machine = Deterministic Turing machine
Explore the equivalence between nondeterministic and deterministic Turing machines by learning how to simulate nondeterministic behavior with a deterministic approach. This lesson covers the use of breadth-first traversal on execution trees and practical implementation in Python, deepening your grasp of Turing machine simulations.
Equivalence of a nondeterministic vs. deterministic Turing machine
With the notion of encoding, we can show how to simulate a nondeterministic Turing machine (NTM) with a deterministic one. A nondeterministic Turing machine is one where there are multiple choices for combinations of current state and character:
In other words, for s, is a relation. To simulate an deterministically, we employ a breadth-first traversal of the tree of ...
