“The optimist proclaims that we live in the best of all possible worlds;
and the pessimist fears this is true.”
-James Branch Cabell, The Silver Stallion
Over the last century, our information society has witnessed the emergence of a new method of scientific inquiry underpinned by Applied Mathematics. Our understanding of complex systems such as the Earth’s weather, the financial market, or social networks, to name a few, is based around mathematical modeling, simulation, and optimization. Modeling and simulation deal with an accurate identification and replication of the underlying processes. Optimization addresses the characterization and computation of actions to achieve a best possible outcome. Mathematical optimization has been present throughout the history of humankind. From Queen Dido’s legend and the isoperimetric problem, going through Fermat’s principle of least time in 1662, until the 20th century development of optimal control theory by Bellman and Pontryagin, the synthesis of optimal actions has been a formidable mathematical challenge.
