I would like to learn how APOC's PageRank algorithm is implemented code-wise. I have checked its GitHub (https://github.com/neo4j-contrib/neo4j-apoc-procedures), searched all files for the keyword
pagerank, but didn't find a real implementation. I assume the implementation should be in Java (*.java files).
Sorry if this question seems naive. Did I miss something basic that everybody should know but I don't?
