“The single most basic form of expression that humans draw upon is imitation of others, and so I think having an original idea may qualify you as being partially insane.”

Ambros Gleixner gives the first keynote of #cpaior2026 on the numerical correctness of MILP solvers. By solving LP relaxations, MILP solvers may need variables with long representations. That is at odds with the use of floating-point arithmetic, which begets the use of tolerance parameters. 1/N
"[L'invention mathématique] ne consiste pas à faire de nouvelles combinaisons avec des êtres mathématiques déjà connus. Cela, n’importe qui pourrait le faire, mais les combinaisons que l’on pourrait former ainsi [...]" – Henri Poincaré (1854-1912) #citation #mathématiques #invention #maths #math
![Portrait photographique de Henri Poincaré, et une citation : "[L'invention mathématique] ne consiste pas à faire de nouvelles combinaisons avec des êtres mathématiques déjà connus. Cela, n’importe qui pourrait le faire, mais les combinaisons que l’on pourrait former ainsi seraient en nombre infini, et le plus grand nombre serait absolument dépourvu d’intérêt. Inventer, cela consiste précisément à ne pas construire les combinaisons inutiles et à construire celles qui sont utiles et qui ne sont qu’une infime minorité. Inventer, c’est discerner, c’est choisir."](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:bem2n5mbgyevwu3blbm4jslr/bafkreiafe222eax7dosnq5pziwmd4fostydjumhwcnwixlkczuqxcwg5ja)

OpenAI's claim that this is a central conjecture in discrete geometry is not an exaggeration. This will I think be looked back on as the first time that AI solved a major mathematics problem (defined as a problem that all experts in some subfield had thought about). openai.com/index/model-...
An OpenAI model has disproved a central conjecture in discrete geometry
An OpenAI model solved the 80-year-old unit distance problem, disproving a major conjecture in discrete geometry and marking a milestone in AI-driven mathematics.

The sunlight-collecting organelles known as chloroplasts solve a packing problem: how to optimize photosynthesis without sustaining damage from dangerously intense rays.

For a decade it was open whether Frank-Wolfe's O(1/√ε) rate on strongly convex sets is tight. We show it is: Ω(1/√ε), even for a simple quadratic on a unit ball.

A similar technique is used for solving both Integer Programs and Constraint Programs: the problem is successively divided into smaller subproblems (branching) that are solved recursively.

Multiple AI systems won gold medals at the 2025 International Mathematical Olympiad (IMO). Exciting as that sounds, @GregHBurnham argues that it represents little progress: an unlucky draw of problems made the event relatively uninformative. Is that cope? Judge for yourself. 🧵
