TreeWidthSolver.jl

Stable Dev Build Status Coverage

TreeWidthSolver.jl is a Julia package for solving the minimal treewidth and the corresponding tree decomposition of graphs. Currently we implemented the Bouchitte-Todinca algorithm[^Bouchitté][^Korhonen], which is a dynamic programming algorithm for solving the exact minimal treewidth problem of graphs. This package is used as a bacakend of OMEinsumContractionOrders.jl for finding the optimal tensor network contraction order.

For more details about this pacakage please see the docs, and please refer to this blog for more about the algorithm we implemented.
