Dr. Ampl is an AMPL-based optimization problem analyzer which may be used either as a stand-alone tool or hooked to a server such as NEOS. The capabilities of this analyzer include classification of the problem at hand, analysis of the objective and constraint functions and their variables, the providing of upper and lower bounds on the values of these functions over the feasible set and assessment of convexity. Two antagonistic approaches are considered for the latter point; namely a convexity disprover and a convexity prover.
