We present a number of improvements of the basic variant of the arc-flag acceleration (Lauther, 1997, 2004) for point-to-point (P2P) shortest path computations on large graphs. Arc-flags are a modification to the standard Dijkstra algorithm and are used to avoid exploring unnecessary paths during shortest path computation. We assume that for the same input graph the shortest path problem has to...
