- MUQ (MIT Uncertainty Quantification) is a C++ and Python framework for performing uncertainty quantification with complex computational models, and for developing new algorithms that exploit model structure. It contains a range of algorithms for Bayesian inference, Markov chain Monte Carlo (MCMC), uncertainty propagation, surrogate building, optimization, and sensitivity analysis, and for integrating these algorithms with ODE- and PDE-based computational models. It is distributed under a BSD license.
