Interactive Minimization Tools based on MINUIT
Project description
iminuit
Interactive IPython Friendly Mimizer based on SEAL Minuit. (It’s included in the package no need to install it separately)
It is designed from ground up to be fast, interactive and cython friendly. iminuit extract function signature very permissively starting from checking func_code down to last resort of parsing docstring(or you could tell iminuit to stop looking and take your answer). The interface is inspired heavily by PyMinuit and the status printout is inspired by ROOT Minuit. iminuit is mostly compatible with PyMinuit(with few exceptions). Existing PyMinuit code can be ported to iminuit by just changing the import statement.
In a nutshell,:
from iminuit import Minuit
def f(x,y,z):
return (x-2)**2 + (y-3)**2 + (z-4)**2
m = Minuit(f)
m.migrads()
print m.values #{'x':2,'y':3,'z':4}
print m.errors
Install
python setup.py install
or from pip:
pip install iminuit
Tutorial
All the tutorials are in tutorial directory. You can view it online too.
Hard Core Cython tutorial. If you need to do a huge likelihood fit that need speed. This is for you. If you don’t care, just use dist_fit. It’s a fun read though I think.
