    Abstract = {In this demo, we will present Tiresias, the first how-to query
    engine. How-to queries represent fundamental data analysis questions of
    the form: ``How should the input change in order to achieve the desired
    output''. They exemplify an important Reverse Data Management problem:
    solving constrained optimization problems over data residing in a DBMS.
    Tiresias, named after the mythical oracle of Thebes, has complex
    under-workings, but includes a simple interface that allows users to load
    datasets and interactively design optimization problems by simply
    selecting actions, key performance indicators, and objectives. The user
    choices are translated into a declarative query, which is then processed
    by Tiresias and translated into a Mixed Integer Program: we then use an
    MIP solver to find a solution. The solution is then presented to the user
    as an interactive data instance. The user can provide feedback by
    rejecting certain tuples and/or values. Then, based on the user feedback,
    Tiresias automatically refines the how-to query and presents a new set of
    results.},
