New paper traces Muddy Children Puzzle origins over 200 years
Epistemic logic classic finally gets a full historical deep dive...
Deep Dive
Hans van Ditmarsch's June 2026 arXiv paper (2606.13703) traces the Muddy Children Puzzle's origin through two centuries of logical and literary publications. This puzzle about knowledge and ignorance has been inspiring for the development of epistemic logic and inspired numerous variations such as involving numbers or coloured hats. The paper also presents a novel hats puzzle involving self-reference.
