Seeded graph matching for the correlated Gaussian Wigner model via the projected power method
Ernesto Araya, Guillaume Braun, Hemant Tyagi
In the \emph{graph matching} problem we observe two graphs and the goal is to find an assignment (or matching) between their vertices such that some measure of edge agreement…
