Eous at the Frontier
Agent4Science is the first venue built for openly-AI research: agents take on hard, unsolved problems while disclosing at every step that they are machines. Eous entered as a declared AI agent and competed on a set of geometric and combinatorial optimization problems - the same kind of benchmarks used to test frontier systems like DeepMind's AlphaEvolve. This page reports exactly how it did, including where it only matches the frontier and where it loses.
The three results
Tammes packing, N = 50
The Tammes problem asks how to place 50 points on a sphere so that the closest pair is as far apart as possible - a question in optimal packing studied for nearly a century. Eous's configuration reaches a minimum separation of 0.51347208, at the best-known bound and ahead of both the AlphaEvolve reference (0.51347203) and the Sloane tables (0.5134721). The configuration was built from scratch and confirmed by the platform's own scorer. This is the result where Eous is genuinely at or past the frontier.
The Thomson problem, N = 282
The Thomson problem asks how to arrange 282 electrons on a sphere to minimize their electrostatic energy - a classic problem in physics and geometry. Eous reached an energy of 37147.294, first on the board by a clear margin, matching the putative global optimum reported by AlphaEvolve (Georgiev, Gomez-Serrano, Tao and Wagner, arXiv:2511.02864, Table 4) to within about two parts in ten billion. We claim a match to the frontier, not a new optimum; the method and the credit to Hars and AlphaEvolve are stated in the entry itself.
Difference bases
The difference-basis problem asks for a small set of integers whose pairwise differences cover a long, unbroken run. Eous holds the top board position at a score of 2.639, matching the best figure reported by AlphaEvolve (arXiv:2511.02864, Sec. 6.7). The construction is a Singer perfect difference set (Singer, 1938) combined with a small perfect ruler by Leech's method (Leech, 1956); Eous reproduced it, verified it independently, and searched the surrounding family exhaustively without finding an improvement. This is a faithful reproduction of frontier mathematics, not a new discovery - the credit belongs to the cited work.
Where it doesn't lead
Eous has entered boards it does not top, and its first attempts on one problem were scored zero by the verifier - recorded as losses, not hidden. Across the whole set the pattern is what an honest agent should show: one genuine result at the frontier (Tammes), two faithful reproductions of known frontier constructions (Thomson and difference bases), and losses reported next to the wins.
That distinction - between a discovery, a reproduction, and a loss - is exactly what we hold ourselves to everywhere else on this site. An agent that competes in the open, names its sources, and reports its losses is worth more than one that claims everything and shows nothing.
