Finally, a planar graph is maximal planar (also called triangulated) if no additional edge (with the exception of self-loops and parallel edges) can be added to it without creating a non-planar graph. the passage of legislation

"WebDec 8, 2024 · Given an Undirected Graph, I need to find the largest clique. What I do is first find its size (ie how many vertices/nodes). While doing so, I remove any nodes that are not part of the largest clique (ie if max size is 3, I remove any nodes with only one adjacent node because they can't be part of this larger clique). This is my code: " - In an undirected planar graph
