OMEinsumContractionOrders: A Julia package for tensor network contraction order optimization

OMEinsumContractionOrders (One More Einsum Contraction Orders, or OMECO) is a Julia (Bezanson et al., 2012) package that implements state-of-the-art algorithms for optimizing tensor network contraction orders.OMECO is designed to search for near-optimal contraction orders for exact tensor network contraction.It provides a comprehensive suite of optimization algorithms for tensor network contraction orders, including greedy heuristics, simulated annealing, and tree-width solvers.This paper presents the key features of OMECO, its integration with the Julia ecosystem, and performance benchmarks.
