A distance-time graph shows how the distance travelled by an object changes over time and can be used to calculate the speed of the object. A sloping line on a distance-time graph shows that the ...

Each line segment of a distance-time graph ... of speed, distance and time as well as how to work out the gradient of a straight line, in order to interpret distance-time graphs.

Abstract: Comparing large graphs using graph edit distance is a time-consuming or even intractable problem ... Main contribution of the present paper is to substantially speed up the computation of ...

(30 seconds for one graph) Due to the time limitation, for comparison between graphs which contains more than 20 nodes, it's hard to compute the exact Graph Edit Distance in 30 seconds ... it can help ...

Abstract: Various sequential algorithms for the shortest path problem on time dependent graphs are appearing in the literature ... For the shortest path problem with time dependent flow speed model, ...
