surjective function 中文意思是什麼
-
A k - role assignment of graph is an assignment of role, if g is a graph, a k - role assignment is a surjective function mapping each vertex into a positive integer 1, 2. . . k, so that if x and y have the same role, then the sets of roles assigned to their neighbors are the same
-角色分配就是一個角色分配,也稱為角色染色。 g是一個圖, -角色分配就是把圖上各頂點映到正整數{ 1 , 2 , … , }的一個滿射函數,它滿足:如果x和y有相同角色,那麼與之相鄰接的點的角色集合也相同。 -
Everett and borgatti introduced the concept : k - role assignment of graph. if g is a graph, a k - role assignment is a surjective function mapping each vertex into a positive integer 1, 2. . . k, so that if x and y have the same role, then the sets of roles assigned to their neighbors are the same
對于圖g ,它的一個k -角色分配就是由各頂點映到正整數1 , 2 , … , k的一個函數,它滿足:如果x和y有相同角色,那麼分配到它們鄰接點的角色的集合也相同。
