SOME NEW RESULTS ON THE MAXIMUM GROWTH FACTOR IN GAUSSIAN ELIMINATION
by Alan Edelman and John Urschel (https://arxiv.org/abs/2303.04892)
Understanding and bounding the growth factor for Gaussian elimination has intrigued mathematical numerical linear algebraists for many decades. It is one of those beautiful problems that is quite easy to state, and yet we still know so very little, especially in the context of complete pivoting. This may seem even more surprising as the problem has been around for more than six decades.
Remark: filenames format example: n11_11p0504.jld means there is an 11x11 matrix with growth 11.0504
