Small week, sharp results 🔓 10 results were added across 6 topics: quantum codes, coins packed in a jar, a test for AI models that read genes, and faster grid math.
Welcome to our 3 new names: circuspulga, jorgy72-sine and nukewire! In all, 7 names got credit this week.
Right now 414 entries are waiting for review. The maintainer also added 761 new problems to the list of open problems. Pick one and liberate it. Let's go 🔥
- Quantum codes that share entanglement and use qutrits, not qubits. Better codes fix more errors. calgulbenkian pushed one code's error-catching distance from 7 to 8, and abshalom-dayan filled gaps like 13-19 with a 14 🔥 Details
- Fitting thousands of equal coins inside one round jar. nukewire and jorgy72-sine each beat the table, like 3949 coins that are slightly bigger than the table listed 🪙 Details
- Codes where every word has the same weight: how many words can fit? ada95ftw lowered the ceiling for one case from 109 to 106 📉 Details
- Spreading 62 points on a ball in 30 dimensions so they sit as far apart as they can. calgulbenkian found a slightly better spread than the table listed 🎯 Details
- A test of AI models that read genes. circuspulga ran a better pooled test: the gap between the top two models on the histone tasks, 0.4807 vs 0.4750, could just be noise 🧬 Details
- Recipes that multiply grids of numbers, the math inside AI and graphics, in fewer steps. mizopl added a new one. This is theory, not a faster program 🧮 Details
