About:
Minuit2 is a C++ library for multidimensional function minimization, widely used in physics data analysis. It implements robust algorithms like Migrad, Simplex, and Scan to find function minima and parameter uncertainties. Its main value is providing reliable optimization for complex scientific models where precision and performance are critical.
Key Features:
  • Migrad algorithm for efficient function minimization
  • Simplex method for derivative-free optimization
  • Parameter uncertainty estimation
  • Support for constrained minimization
  • Object-oriented C++ interface
Use Cases:
  • Fitting physics models to experimental data
  • Optimizing complex simulation parameters
  • Statistical analysis and parameter estimation
  • Algorithm comparison and benchmarking
Alternatives:
  • GSL (GNU Scientific Library) – Provides broader numerical routines but Minuit2 is specialized for high-energy physics fitting
  • SciPy optimize – Python-based alternative, less suitable for C++ physics frameworks
