Two graphs,G1andG2, are isomorphic if there exists a permutation of the nodesPsuch thatreordernodes(G2,P)has the same structure asG1. Two graphs that are isomorphic have similar structure. For example, if a grap
5,10). DSGRN associates to a network an ODE model with piece-wise constant monotone nonlinearities consistent with the network structure. Since the nonlinearities only assume finite number of values, there are two important simplifications compared to a general ODE model....
In the Switching Tower of Hanoi interpretation of Sierpiński graphs Spn, the P2 decision problem is to find out whether the largest moving disc has to be transferred once or twice in a shortest path between two given states/vertices. We construct an essentially optimal algorithm thus extending ...
