algorithmsfolder contains the GSQL implementation of all the graph algorithms offered by the library. Within the algorithms folder are six subfolders that group the algorithms into six classes:
graphsfolder contains small sample graphs that you can use to experiment with the algorithms. In this document, we use the test graphs to show you the expected result for each algorithm. The graphs are small enough that you can manually calculate and sometimes intuitively see what the answers should be.
pageRank, you could run it from GSQL as below:
