Efficient Matching in Large DAE Models
ACM Transactions on Mathematical Software (TOMS), Volume 50, Issue 3Article No.: 18, Pages 1–25https://doi.org/10.1145/3674831This article presents a matching algorithm for bipartite graphs containing repetitive structures and represented by intension as Set-Based Graphs. Under certain conditions on the structure of the graphs, the computational cost of this novel algorithm is ...
