Tensor Rank as a Predictor of Dynamical Tractability — A* search for optimal decomposition of coupled systems
A research repo into differentiable algorithm search for 3x3 matmul
Autonomous mathematical research by Qiushi Engine: a structural tensor-rank lower bound of 21 for 3x3 matrix multiplication over F2, with complete Lean formalization, bilingual reports, and an open research trajectory.
Exact tensor and bilinear rank over finite fields: lower bounds, exhaustive search, SAT with DRAT-checkable refutations, symmetry reduction, and operator sparsification proved minimal against PLinOpt, with a local web console. C++20 on Givaro.
