about forward motion dataset,MDS performance is worse than colmap's original view selection algorithm

[yuancaimaiyi]

@rajkataria I tried vehicle data and found that the mds algorithm did not perform well. And I adjusted the parameters and still didn’t improve much aam_matches += pow(0.5, point_correspondences.size()-1); float tau_value = 2.0;

so ,What do i need to do? thanks
