Refining with colors. Mathematicians have developed various strategies to compare graphs. Since the 1970s, algorithms have been able to test graph isomorphism, but in exponential time.

A horizontal line on a distance-time graph shows that the object is stationary close stationary Not moving or at rest., or not moving, because the distance does not change as time changes.
