When using his method, twice as many digits ... should be the fundamental speed limit—that no possible multiplication algorithm could do better than this. The paper has not yet been peer ...

Matrix multiplication ... algorithm for multiplying 4×4 matrices, which reduces the number of steps necessary to perform a matrix calculation. For example, multiplying two 4×4 matrices together ...

Thus, many researchers have investigated AMM algorithms, which trade off accuracy of matrix multiplication for speed. The key innovation with MADDNESS is using a pre-processing step to produce ...
