英文摘要 | In this paper, we consider rainbow connection number of maximal outerplanar graphs (MOPS) on algorithmic aspect. For the (MOP) G, we give sufficient conditions to guarantee that rc(G) = diam(G). Moreover, we produce the graph with given diameter D and give their rainbow coloring in linear time. X. Deng et al. [4] give a polynomial time algorithm to compute the rainbow connection number of MOPS by the Maximal fan partition method, but only obtain a compact upper bound. J. Lauri [11] proved that, for chordal outerplanar graphs given an edge-coloring, to verify whether it is rainbow connected is NP-complete under the coloring, it is so for MOPs. Therefore we construct Central-cut spine of MOP G, by which we design an algorithm to give a rainbow edge coloring with at most 2rad(G) + 2 + c, 0 <= c <= rad(G) - 2 colors in polynomial time.
