This paper promotes an AI-VCR technology of searching without information. VCR is an extension of FCR(Fixed Carrying Rules) which is also computation rules of FCN(Fixed Carrying Numbers). The FCN are some special examples of VCN(Variable Carrying Numbers). DFS(Depthfirst Search) is a blind searching without information. In AI-VCR technology, AI(Artificial Intelligence) is used in dynamic designing computation rules of VCN. Both FCR and VCR in searching without information are variables of nodes’ depth function. Finally, it gives out some examples of problem-solving method, namely problem-solving such as catching fish with casting a net or herdsman picks peaches with his fierce-looking before climbing up a tree.
