Class cohesion refers to the degree of the relatedness of the members in a class. It is considered as one of most important object-oriented software attributes. Several metrics have been proposed in the literature in order to measure class cohesion in objectoriented systems. They capture class cohesion in terms of connections among members within a class. The major existing class cohesion metri...

The quality of the software design has a considerable impact on software maintainability. Improving software quality can reduce costs and efforts of software maintenance. Cohesion, as one of software quality characteristics, can be used as an early indicator for predicting software maintenance efforts. This paper improves Martin’s cohesion metric, which is one of the well-known and wellaccepted...

AbstractGrammatical Evolution (GE) is one of the most popular Genetic Programming (GP) variants, and it has been used with success in several problem domains. Since original proposal, many enhancements have proposed to GE order address some its main issues improve performance.In this paper we propose Probabilistic Grammatical (PGE), which introduces a new genotypic representation mapping mechan...

A hypothesis to explain the maternal age-dependent increase in formation of aneuploid eggs is deterioration of chromosome cohesion. Although several lines of evidence are consistent with this hypothesis, whether cohesion is actually reduced in naturally aged oocytes has not been directly tested by any experimental perturbation. To directly target cohesion, we increased the activity of separase,...
