The Existence of(K2,3+e-optimal Packing of λKv
摘要/Abstract
摘要:
讨论了2类6点7边图Gi=K2,3+e(i=1,2)的最优填充存在性问题。证明了:存在(v,Gi,λ)-OPD当且仅当v≥6,除去非最优P(6,Gi,1)=1及未知的(9,Gi,1)-OPD,i=1,2。
Abstract:
The existence of Gi-optimal packing is discussed,whereGi=K2,3+e(i=1,2) has six vertices and seven edges.The result is obtained:(v,Gi,λ)-OPD existiff v≥6,with the not optimal values P(6,Gi,1)=1,and the probably exceptional values(9,Gi,1)-OPD,i=1,2.
