[ A B C B C A C A B] formed by swapping the last two rows might be considered equivalent (for a given purpose). We see the second one is in reduced form, i.e., the first row and first column are in the same order. So, we might regard this as a canonical form. However, in the Latin square case, there ...
WebIn this example, we empirically study a random-order first improvement algorithm for the TSP that is based on the 2-exchange neighbourhood. This algorithm always starts from the same initial tour, which visits the vertices of the given graph in their canonical order (i.e., in the order v 1, v 2, …, v n, v 1). WebFeb 1, 2005 · An interesting application in graph drawing are visibility representations for triangular graphs. Zhang and He [2005a] construct an st-ordering from a canonical ordering tree to guarantee a bound ...
WebApr 30, 2005 · In this paper we consider the problem of determining a balanced ordering of the vertices of a graph; that is, the neighbors of each vertex v are as evenly distributed to the left and right of v as possible. This problem, which has applications in graph drawing for example, is shown to be NP-hard, and remains NP-hard for bipartite simple graphs with … WebAbstract. Canonical ordering is an important tool in planar graph drawing and other applications. Although a linear-time algorithm to determine canonical orderings has …

A canonical form is a labeled graph Canon(G) that is isomorphic to G, such that every graph that is isomorphic to G has the same canonical form as G. Thus, from a solution to the graph … See more Clearly, the graph canonization problem is at least as computationally hard as the graph isomorphism problem. In fact, graph isomorphism is even AC -reducible to graph canonization. However it is still an open question whether … See more Graph canonization is the essence of many graph isomorphism algorithms.
