This paper discusses the multi-signal flow graph model and the testability analysis method based on this model. The modeling process of the multi-signal model, the dependency matrix generation method of the failure-test and the details of the testability analysis are illustrated by use of several examples. The results got in the testability analysis are also validated. It is demonstrated that the...
For a program with many statements and complex structures, the testing have a lot of trouble, such as program analysis difficulties and need complex test cases, etc. This paper propose a method of dividing the program under test (PUT) into a several program segments with small cyclomatic complexity. This paper analyzes the relationship between the input variables and the fragments, gives the approach...
Connected dominating set (CDS) has a wide range of applications in wireless ad hoc networks. A number of distributed algorithms for constructing a small CDS in wireless ad hoc networks have been proposed in the literature. The majority of these distributed algorithms follow a general two-phased approach. The first phase constructs a dominating set, and the second phase selects additional nodes to...
In this paper, a kind of the creative design method that intelligently optimizes the hierarchical structure product has been studied and proposed based on genetic algorithm. Key technology about the improved genetic algorithm is applied to the multi-level complicated mechanical structure scheme design has been discussed based on many hierarchical structure describes, prevented the standard genetic...
