A cyclic graph is a type of graph in which at least one path forms a cycle, meaning you can start at one vertex, follow the edges, and return to the same vertex without retracing any edge. This characteristic distinguishes cyclic graphs from acyclic graphs, which do not contain any cycles. Cyclic graphs can be directed or undirected, depending on whether the edges have a direction. Cyclic graphs are commonly used in various fields, including computer science and mathematics, to model relationships and processes. For example, they can represent networks, such as social networks or transportation systems, where connections loop back on themselves. Understanding cyclic graphs is essential for analyzing complex systems and algorithms, such as those used in graph theory and network analysis.
