Nonlinear regression / Curve fitting with L-infinity norm
...gression using the least squares estimation method in R (nls function), but I haven't found any packages that implement nonlinear regression with the L-infinity norm.
I have found literature on the subject, but haven't yet had the chance to read it through:
