abstract

Moosbauer and Poole have recently shown that the multiplication of two $5\times 5$ matrices requires no more than 93 multiplications in the (possibly non-commutative) coefficient ring, and that the multiplication of two $6\times 6$ matrices requires no more than 153 multiplications. Taking these multiplication schemes as starting points, we found improved matrix multiplication schemes for various rectangular matrix formats using a flip graph search.

  1. Exploring Commutative Matrix Multiplication Schemes via Flip Graphs

    cs.SC 2025-06 conditional novelty 6.0 of 10

    A commutative flip graph defined on a quotient tensor space recovers known commutative matrix multiplication bounds up to 5x5 without improving any of them.

  2. Higher order Jacobi method for solving system of linear equations

    cond-mat.supr-con 2025-05 reject novelty 2.0 of 10

    The higher order Jacobi method is a known repeated-squaring restatement of Jacobi iteration framed as a neural network, and the reported near-constant GPU scaling is not credible.
