The paper introduced cooperative co-evolutionary algorithms and distributed co-evolutionary algorithms to the torpedo conceptual design,at the end,the two models were analyzed with there own properties.

A new theory about torpedo general design;

This paper pressents a collaborative optimization model for torpedo general design based on the developing multidisciplinary design optimization (MDO) .

Dividing the torpedo general design into seven subjects based on collaborative optimization(CO),a method of MDO in torpedo general design is proposed and analyz.

Discussion on the tunnel route geometric design of express highway;

The union opens the zhangshi highway Baoding section location,from the route selection principle,the plane linear,the longitudinal section geometric design,carries on the discussion to the mountainous area highway geometric design.

The paper discussed the concept of the operating speed and its application to geometric design.

A brief talk on the alignment design of the old road rebuilding;

Prediction model of possible velocity in highway alignment design;

Linear designing is one of the basic aspects of tunnel construction and safety control.
