Is there a high quality nonlinear programming solver for Python?
Weboptimoptions ( 'fmincon') returns a list of the options and the default values for the default 'interior-point' fmincon algorithm. To find the default values for another fmincon algorithm, set the Algorithm option. For example, opts = optimoptions ( 'fmincon', 'Algorithm', 'sqp') WebDec 1, 2011 · The method which requires the fewest function calls and is therefore often the fastest method to minimize functions of many variables is fmin_ncg. This method is a modified Newton’s method and uses a conjugate gradient algorithm to (approximately) invert the local Hessian. WebMar 8, 2013 · The open source Python package, SciPy, has quite a large set of optimization routines including some for multivariable problems with constraints (which is what fmincon does I believe).
