WebIt is supposed to implement the Hopcroft and Tarjan algorithm in order to test whether a graph is planar or not. In order to implement the algorithm, I decided to follow the paper of William Kocay, The Hopcroft-Tarjan Planarity Algorithm (October 1993). WebThat said, we're well positioned to approve Tarjan's bound. In fact, the template of the proof is going to very much mirror what we already did for the log star analysis by Hopcroft and Ullman. So in that spirit, let's review what were the two basic workhorses, the two building blocks that drove forward the Hopcroft-Ullman analysis.
