MINUIT
MINUIT, now MINUIT2, is a numerical minimization computer program originally written in the FORTRAN programming language〔http://wwwasdoc.web.cern.ch/wwwasdoc/minuit/minmain.html〕 by CERN staff physicist Fred James in the 1970s. The program searches for minima in a user-defined function with respect to one or more parameters using several different methods as specified by the user. The original FORTRAN code was later ported to C++ by the ROOT project; both the FORTRAN and C++ versions are in use . The program is very widely used in particle physics, and hundreds of published papers cite use of MINUIT.〔http://inspirehep.net/search?ln=en&p=refersto%3Arecid%3A101965〕 In the early 2000s Fred James started a project to implement MINUIT in C++ using object-oriented programming. The new MINUIT is an optional package (minuit2) in the ROOT release. the latest version is 5.34.14, released on 24 January 2014.〔(Home page for new C++ MINUIT )〕 There is also a Java port〔(Java port of MINUIT project )〕 as well as several Python ports.〔(PyMinuit - Python port of MINUIT project )〕〔(IMinuit - Interactive IPython Friendly Mimizer based on SEAL Minuit )〕
MINUIT is not a program that can be distributed as an executable binary to be run by a relatively unskilled user: the user must write and compile a subroutine defining the function to be optimized, and oversee the optimization process.
