2025-03-06
This article demonstrates solving the classic Knights and Knaves logic puzzle from the movie *Labyrinth* using Boolean algebra. The author models the problem, using A for the answer, Q for the correct answer to the question, and G for whether the goblin is lying, deriving A = G⊕Q. By cleverly crafting the question to incorporate the other goblin's lying status, the equation simplifies, revealing the solution. The author argues that the formalized approach clarifies the steps and highlights the usefulness of formal systems as reasoning tools.
