Use minimax to minimize the worst-case value of a set of objective functions. Note that if parameters are bounded and one or more of the estimates are at their bounds, then those estimates are regarded as fixed. Each function differs in how it computes the slopes of the interpolant, leading to different behaviors when the underlying data has flat areas or undulations. Web browsers do condition. that is, P(xj)=yj, and the first derivative dPdx is continuous. Write objectives and constraints with expressions of optimization variables.
