  "Description": "An efficient C++ based implementation of the 'DEoptim'\nfunction which performs global optimization by differential\nevolution. Its creation was motivated by trying to see if the\nold approximation \"easier, shorter, faster: pick any two\" could\nin fact be extended to achieving all three goals while moving\nthe code from plain old C to modern C++.  The initial version\ndid in fact do so, but a good part of the gain was due to an\nimplicit code review which eliminated a few inefficiencies\nwhich have since been eliminated in 'DEoptim'.",
