A temporal graph with lifetimeLis a sequence ofLgraphs, called layers, all of which have the same vertex setVbut can have different edge sets. The underlying graph is the graph with vertex setVthat contains all the edges that appear in at least one layer. The temporal graph is always connected if each layer is a connected graph, and it isk-edge-deficient if each layer contains all except at mostkedges of the underlying graph. For a given start vertexs, a temporal exploration is a temporal walk that starts ats, traverses at most one edge in each layer, and visits all vertices of the temporal graph. We show that always-connected,k-edge-deficient temporal graphs with sufficient lifetime can always be explored intime steps. We also construct always-connected,k-edge-deficient temporal graphs for which any exploration requirestime steps. For always-connected, 1-edge-deficient temporal graphs, we show thatO(n) time steps suffice for temporal exploration.
