Towards a polynomial algorithm for optimal contraction sequence of tensor networks from trees
The computational cost of contracting a tensor network depends on the sequence of contractions, but to decide the sequence of contractions with a minimal computational cost on an arbitrary network has been proved to be an NP-complete problem. In this work, we conjecture that the problem may be a pol...
