摘要 对于图G_1、G_2,2色广义Ramsey数R(G_1,G_2)是指最小正整数P,使得每一个p阶的图G,或者G包含G_1,或者G的补图包含G_2。用改进的模拟退火算法求解得到了R(W_m,K_n),R(B_m,K_n),R(F_m,K_n),类型的一些Ramsey数的下界。 For given graphs G1,G2,the 2-color Ramsey number R(G1,G2) is defined to be the least positive integer p such that every 2-coloring of the edges of complete graph Kp contains a monochromatic copy of Gi colored with i,for 1≤i≤2.With the help of simulated annealing algorithm,some lower bounds of Ramsey numbers for the families R(Wm,Kn),R(Bm,Kn),R(Fm,Kn) is obtained.
