264, diamond search algorithm, hexagon-based search algorithm, unsymmetrical-cross multi-hexagon search algorithm and full search algorithm were analyzed base on X264 of the pure C language.

The result of research shows that the DABP algorithm can enhance the speed of convergence,the calculation precision,the ability of global search and the forecast ability of the network.

The results show that compared with the traditional ACA,the improved ACA has more global search capability and robu.

On the one hand,the hybrid algorithm provides global search(reliability) by means of the promotion of high levels of population diversity.

An optimization combination genetic algorithm based on the dual operator is developed in order to remedy the influence on the variety of population by combining other operator with better global searching ability.

A modified particle swarm optimization (PSO) algorithm was adopted to optimize functions, which overcame the shortcoming of converging to local optimum for PSO algorithm, increased the converging rate and achieve the global searching.

In order to improve the searching precision and the global searching ability of evolutionary strategy(ES),this paper proposed an adaptive evolutionary strategy based on the feedback and sharing mechanism(ESBFSM),in which the information of every generation\'s current optimal searching result and sharing degree was fed into the mutating formula.

In order to realize the full information management of the project material database,and the advanced inquiry based on the full information management of material information especially full text search,this paper analyzes the system function,and realizes the project material database system based on the full information management.

SQL Server full text search support can query both pure text fields and unstructured binary fields.

The exact best matching may be found by a full search.
