  1. Formalizing R(3,3)=6 in Rocq

    Machine-verified proof of the friends and strangers theorem using computational brute force in Rocq.

  2. ZX-Calculus: Rewriting Your Way to Smaller Circuits

    ZX-calculus turns quantum circuits into flexible graphs. Simple rewrite rules yield provably equivalent - often smaller - circuits.

  3. Buzen's Algorithm

    12 billion states reduced to 500 operations. How a 1973 algorithm makes closed queueing networks tractable.

  4. Goodstein Sequences

    A simple arithmetic process that grows faster than any computable function, yet always terminates - and this fact is unprovable in standard arithmetic.

  5. Quantum Counterfeit Coins

    A quantum algorithm for the counterfeit coin problem using Bernstein-Vazirani, achieving O(1) query complexity vs classical O(log N).
