A new concept of weighted pair graphs (WPGs) is proposed to represent a new reconstructibility definition for Boolean control networks (BCNs), which is a generalization of the reconstructibility definition given in Definition 4 in [E. Fornasini and M. Valcher, IEEE Trans. Automat. Control, 58 (2013), pp. 1390--1401]. Based on the WPG representation, an effective algorithm for determining the new reconstructibility notion for BCNs is designed with the help of the theories of finite automata and formal languages. We prove that a BCN is not reconstructible iff its WPG has a complete subgraph. In addition, we prove that a BCN is reconstructible in the sense of Definition 4 in [E. Fornasini and M. Valcher, IEEE Trans. Automat. Control, 58 (2013), pp. 1390--1401] iff its WPG has no cycles, which is simpler to check than the condition in Theorem 4 in [E. Fornasini and M. Valcher, IEEE Trans. Automat. Control, 58 (2013), pp. 1390--1401].
