WebOct 19, 2024 · This has to do with the storage of the graph in memory. Graphs tend to be very large data structures, and for some applications such as knowledge representation, they may end up being untreatable unless we take precautions. One such precaution consists in storing the graph in the format that’s more efficient, in relation to its density. … WebJan 7, 2015 · The matrix representation gives the advantage when the graph is dense, meaning when most of the nodes/vertices are connected to each other. This is because in such cases, by using the entry of matrix, it saves us from having to allocate an extra pointer (which need a word size memory) for each connection. open source political campaign software
