Ulam-Rényi problem on searching with errors and optimal error-correcting codes;

To improve the efficiency of 3D model retrieval,an algorithm for 3D model retrieval based on integer medial axis skeleton was proposed in this paper.

3D model retrieval has recently become one of active research areas in content-based retrieval.

According to the failure mode and shape of slip surface of soil slope and based on limit equilibrium theory,a new searching model was put forward to determine the critical slip surface of soil slope.

Information searching model is the core of modern information searching system .

Based on the model,it researches searching model and its algorithm of special resource,provides monitoring architecture of P2P network,and solves the problem of monitoring special resources of network.

Massive terrain navigation search model based on P2P

The use of optimal search theory in the search model of disappeared tourist is deduced.

Based on the research and study of these and integrated the phenomenon of Small-world in P2P, this paper puts forward a search model of unstructured P2P network based on the Interest.

Most of traditional fault-tolerant model adopt copy and redundance mechanism, therefore a large number of the rubbish is made in system.

Based on the LIP fault-tolerant model and it s three properties,an improved program of getting LIP is proposed.
