Mar 4, 2020 · I think I'm onto some sort of algorithm for untangling planar graphs, I have a method and I don't think there's any graph I couldn't untangle.
Clearly, not every geometric graph can be untangled. So, we assume that G is planar, that is, there exists a drawing without crossing edges.
Mar 4, 2014 · Untangle gives you a graph, ie a set of vertices (points) with edges (lines) between some of them. You are asked to find an embedding of the graph into the two ...

Can you untangle the graph? See if you can position the vertices so that no two lines cross. Number of line crossings detected: 3. 0 moves taken in 5.4s.
Jan 5, 2022 · Any generic planar closed curve with n crossings can be turned into a simple closed curve by applying O(n3/2) homotopy moves without ever ...
