Realization of Breadth-first Searches Based AI Properties of VCN

This paper makes an analyzing & discussing of Breadth-first Search technology of both FCN and VCN in searching without information, and points out that, merits and demerits of two Numbers on searching without information. And then, it gives a novel realization method of Breadth-first Search in problem-solving which sometimes we should think simultaneously over the intelligent properties of VCN, and gives out an example of the problem-solving method, i.e. the problem-solving such as catching fish with casting a net or boy-herder picks peaches by climbing up a tree.
