Let Δ â聣楼 3 be an integer. Given a fixed z â聢聢 +Δ such that zΔ 0, we consider a graph Gz drawn uniformly at random from the collection of graphs with zin vertices of degree i for i = 1,.ï戮 .ï戮 .,Δ. We study the performance of the Karp-Sipser algorithm when applied to Gz. If there is an index Î麓 1 such that z1 =.ï戮 .ï戮 . = zÎ麓-1 = 0 and Î麓zÎ麓,.ï戮 .ï戮 .,ΔzΔ is a log-concave sequence of positive reals, then with high probability the Karp-Sipser algorithm succeeds in finding a matching with n â聢楼 z â聢楼 1/2-o(n1-ε) edges in Gz, where ε = ε (Δ, z) is a constant. |
