2DMAT

  • Level of openness 3 ★★★
  • Document quality 2 ★★☆

2DMAT is a framework for applying a search algorithm to a direct problem solver to find the optimal solution. In  version 1.0, for solving a direct problem, 2DMAT offers the wrapper of the solver for the total-reflection high-energy positron diffraction (TRHEPD) experiment. As algorithms, it offers the Nelder-Mead method, the grid search method, the Bayesian optimization method, and the replica exchange Monte Carlo method. Users can define original direct problem solvers or the search algorithms.
