I am a back-end software engineer specializing in multiple-criteria decision making (MCDM) and mathematical optimization. I nearly always make use of for my heuristic optimization needs (it`s really an excellent piece of software). For numerical optimization, I`m partial to the Levenberg-Marquardt algorithm with modifications . The Levenberg-Marquardt-Transtrum-Sethna (LMTS) algorithm? ©
