对于外平面图G的扩充问题,我们给出了一个最优算法,即通过增加最少的边数来扩充外平面图G,使得扩充后的图G′是外平面2-连通的.当我们要求G′是2-边连通时,我们也最优地解决了同样的问题。
We provide an optimal algorithm for the problem of augmenting an outerplanar graph G by adding a minimum number of edges in such a way that the augmented graph G′ is outerplanar and 2-connected. We also solve optimally the same problem when instead we require G′ to be 2-edge-connected.
