Another difference between directed and undirected graphs is how paths and cycles are defined. A path is a sequence of vertices that are connected by edges, without repeating any vertex or edge.

Imagine a directed graphical model, akin to LinkedIn connections, where skills influence job opportunities, or vice versa. Unlike undirected models, these use directed acyclic graphs (DAGs) to ...

In a directed graph, an edge is typically represented as an ordered pair of vertices, such as (A, B), which means there is a directed edge from vertex A to vertex B.

The following two files (ud_graph.py and d_graph.py) should contain undirected and directed graphs classes and associated methods The UndirectedGraph class should include the following methods ...

Abstract: We consider the problem of information aggregation in sensor networks, where one is interested in computing a function of the sensor measurements. We allow for block processing and study ...
