摘要：
This paper reports work done during an internship at the LHCb experiment at CERN. The task was to implement a Metropolis algorithm as a minimizer for negative log likelihood (nnl) fits into the ROOT Data analysis framework. The Metropolis algorithm is based on a MCMC which w.r.t. previously broadly used algorithm called Minuit can easily be scaled to multidimensional parameter space. Moreover, such kind of algorithms can easily be parallelized.
