Describing Tic-Tac-Toe Using Dependent Sum Types

Problem

Can we use Type Theory to show that a given Petri-Net correctly models a game of Tic-Tac-Toe?

EDIT: removed a bad attempt to grapple with this problem originally in 2017

Explaining Tic-Tac-Toe using Entropy

  • The state space of a game is 9!
  • there are 9 moves per game
  • on average there are 5 degrees of freedom for any given move
  • on average there are 4 previous actions before the 'current turn'
