Brief

Ryan Williams, MIT professor and Gödel Prize winner, is interviewed by Ryan Peterman in a ~1h12m episode published 2026-06-30 that covers solving Leetcode 3SUM faster than popular 'optimal' solutions, SAT problems and solvers, fine-grained complexity and a proposed severe strengthening of P vs NP, simulating space with time, and research-advice; video, audio, and transcript links provided.

Why it matters

Ryan Williams, MIT professor and Gödel Prize winner, was interviewed by Ryan Peterman in an episode published 2026-06-30 that runs about 1:11:56 (chapters include 00:41 Leetcode 3SUM, 17:00 severe strengthening of P vs NP, 24:38 SAT problems, 46:57 simulating space with time).

Key details

  • Williams demonstrates solving the Leetcode 3SUM problem faster than the popular 'optimal' solutions and discusses fine-grained complexity, SAT solvers, and bold 'hot takes' on famous open questions (chapter breakdown provided).

Ryan Williams (@rrwilliams) is a professor at MIT and the winner of the Gödel Prize in theoretical computer science. I interviewed him all about his work starting by asking him a popular Leetcode question (3 SUM).

In this episode:

• Solving Leetcode faster than popular "optimal" solutions
• SAT problems and solvers
• Hot takes on famous open questions
• How to pick good research direction
