Minimum Spanning Tree Verification Under Uncertainty,lue. An . of an input item reveals its exact value. If the exact value is equal to the assumed value, we say that the update . the assumed value. We consider verification under uncertainty for the minimum spanning tree (MST) problem for undirected weighted graphs, where each edge is associated with

The dense substructures witnessing large width are presented in a unified way akin to tangles, as orientations of separation systems satisfying certain consistency axio

We apply recent formulations of time-varying graphs (TVGs) to DMVP, shedding new light on the computational hierarchy . of TVG classes by analyzing them in the context of graph navigation.
