MCTDH-B and MCTDH-F or, together, MCTDH-X are methods for describing correlated quantum systems of identical particles by solving the time-dependent Schr\\\"odinger equation from first principles. MCTDH-X is used to accurately model the dynamics of real-world quantum many-body systems in atomic, molecular, and optical physics. The key feature of these approaches is the time-dependence and optim","authors_text":"Alexej I. Streltsov, Axel U. J. Lode, Camille L\\'ev\\^eque, Lars B. Madsen, Ofir E.
