I can find this lowest point by finding where the slope (the derivative with respect to m) is zero. I know, I know. It is possible for a function to have a zero slope and NOT be a minimum.

A new nonparametric estimate of a convex regression function is proposed and its stochastic properties are studied. The method starts with an unconstrained estimate of the derivative of the regression ...
