It the latest scipy 1.4.1 package we have the BFGS local minimization technique which has as a sub-parameter norm which is set to infinity, the doc says:
norm : float
Order of norm (Inf is max, -Inf is min).
What does this mean? What values can norm take? Should I leave it as Inf, or should I give it some float values and try out which one work better? What happens if I set it to -Inf?
What is the role of this variable in the optimizer?
