WebJan 11, 2024 · The Right Representation: List vs. Matrix. There are two classic programmatic representations of a graph: adjacency lists and adjacency matrices. Both allow the application of the same algorithms, but they differ in performance. I will explain both representations using the following directed example graph: WebView CPSC 221-4.docx from CPSC 221 at University of British Columbia.
