TTNOpt documentation

TTNOpt is a software package that utilizes tree tensor networks (TTNs) for quantum spin systems and highdimensional data analysis.

TTNOpt provides efficient and powerful TTN computations by locally optimizing the network structure, guided by the entanglement pattern of the target tensors.
