DIMACS format

The DIMACS format is a standardized way to represent graph-related data for computational problems. It uses simple text files where nodes (vertices) and connections (edges) are described with specific numbering and labels. For example, in the format for graph problems, lines starting with certain characters indicate the type of data, such as nodes or edges, making it easy for algorithms to read and process complex networks efficiently. This format is widely used in research and programming competitions for tasks like finding shortest paths, network flow, or graph coloring.
