DIRAC'S THEOREM
if G is a simple graph with n vertices with n≧3 such that the
degree of every vertex in G is at least n/2 then G has Hamilton circuit
ORE'S THEOREM
if G is a simple graph with n vertices with n≧3 such that deg(u)+deg(v)≧n
for every pair of nonadjacent vertices u and v in G
then G has Hamilton circuit
想請問這兩個定理要怎樣去理解呢
