(summation over all R@K) is used to evaluate the overall performance. Both WD and GWD can boost the performance of the SCAN model, while WD achieves a larger margin than GWD. This indicates that when used alone, GWD may not be a good metric for graph alignment. When combining the two distances together, GOT achieves the best performance.
