Temporal Graph Exploration

Temporal Graph Exploration (TEXP) is a fundamental problem where one aims to visit every vertex/edge of the temporal graph. The key question is understanding what structural properties make a graph explorable, and how quickly this exploration can be completed.

While explorability can be efficiently determined for static graphs, the problem becomes NP-complete for temporal graphs. Note that in most of the works, agents are typically allowed to wait at a vertex between moves for an unbounded amount of time.

There are two types of exploration considered in the literature:

Vertex Exploration (Hamilton, TSP)

Edge Exploration (Euler)
