This paper founds a 0-1 integral programming model for science and technology project management prob-lem by applying mathematical programming method, researching the object function and constraint conditions, andgives a responsible polynomial approximation algorithm. The software package for decision support is developed, itcan availably solve the realistic problem of planning project.
Routing protocol is one of the kernel technologies of the Internet. The swift and violent development of theInternet enables the study of routing protocols to be an important research direction of computer science. This papershows opening problems in the traditional best-effort model used on Internet that cannot guarantee the quality of ser-vice of the rigid business and gives some studying directions.
Problems of computing the reversal distance between genomes are discussed. Problems of computing the reversal distance between genomes are fundamental problems of Computational Biology, these problems have important meanings in studying the biological race evolution and the bio-pharmaceuticals etc. The problem of evolutionary trees based on reversal distance between genomes and it's NPC property are especially discussed.
