WebAug 2, 2024 · Topological sorting is a proxy for this process so I was curious as to how the topo_sort() function in R would work. It turns out that it produced ‘the answers’ that were ‘correct’. This caused me to question what algorithm was being used to do the sort since I was aware that there could be multiple different sorts. WebJan 17, 2014 · I am somewhat confused by your question since a topo sort that ignores cycles is virtually the same as a regular topo sort. I'll develop the algorithm so that you can handle cycles as you see fit; perhaps that will help. The idea of the sort is: A graph is a collection of nodes such that each node has a collection of neighbours.
