Learn how to detect, avoid, or exploit negative cycles or weights in graph algorithms, and what are some common applications and techniques for shortest paths and maximum flows.

These are paths that loop back to where they started after passing through a series of edges whose weights add up to a negative number. In a graph with negative cycles reachable from the starting ...

Data points are plotted on a graph and then a line of best fit is drawn to show the overall trend, close trend The overall direction of the data. For example, upward or downward. if there is one.

Two non-adjacent nodes usually have different representations, which can be seen as negative samples. Besides the node representations, the structural information of the graph is also crucial for ...
