MinKit is a python package meant to minimize probability density functions (PDFs) in chi-squared and maximum likelihood fits. It also provides tools to calculate and handle parameter errors. The package offers a common interface to use iminuit, SciPy or NLopt minimizers. In order to do numerical integrations, the GSL libraries are used. The utilization of both CPU and GPU devices is supported in MinKit. For GPU backends, it is relied in the Reikna package, that is a common interface for PyCUDA and PyOpenCL. It is not necessary to have the previous packages installed if working only with CPU backends.
