This C++ version of BAT is still being maintained, but addition of new features is unlikely. Check out our new incarnation, BAT.jl, the Bayesian analysis toolkit in Julia. In addition to Metropolis-Hastings sampling, BAT.jl supports Hamiltonian Monte Carlo (HMC) with automatic differentiation, automatic prior-based parameter space transformations, and much more. See the BAT.jl documentation.
BAT Tutorials for version 1.0
Sorry, no verified tutorials at the moment for version 1.0. We are currently working on updating the tutorials.
The tutorials for older BAT versions can be found here.
