It's not just calculator people - two mathematicians improve on an AI's best effort by removing one more multiply step from a 5x5 matrix multiply.

It's a shame, the article does not give the algorithm so efficient that it beats all the previous records.

Quote:In a more complex example, AlphaTensor discovered a new way to perform a 5×5 matrix multiplication in 96 steps (versus 98 for the old method). This week, Manuel Kauers and Jakob Moosbauer published a paper in which they claim to have managed to reduce that number by one step, to 95 multiples.

In the meantime, I continue to use my HP-15C, it only takes four or five steps to achieve the product of two matrices. I find that using 96 steps is far too greedy for such a simple operation.

Sounds like a RISC vs. CISC debate. Wink
Thanks for sharing! Yes I see how AI (or simply new computing methods) are "augmented help", and that's plenty helpful.
