Regression testing is an important and expensive activity that is undertaken every time a program is modified to ensure that the modifications do not introduce new bugs into previously validated code. An important research problem, in this context, is the selection of a relevant subset of test cases from the initial test suite that would minimize both the(More)
Conventional debuggers do not allow users to go back and examine the program states at statements which have already been executed. In case the user wants to examine the program state at a statement which was executed sometime back, he is forced to restart the entire debugging process. To overcome this problem, we examine the issue of reverse execution of(More)
This paper presents a novel approach of generating test cases from UML design diagrams. We consider use case and sequence diagram in our test case generation scheme. Our approach consists of transforming a UML use case diagram into a graph called use case diagram graph (UDG) and sequence diagram into a graph called the sequence diagram graph (SDG) and then(More)
We present an elitist multi-objective genetic algorithm (EMOGA) for mining classification rules from large databases. We emphasize on predictive accuracy, comprehensibility and interestingness of the rules. However, predictive accuracy, comprehensibility and interestingness of the rules often conflict with each other. This makes it a multi-objective(More)
We present a multi-objective genetic algorithm for mining highly predictive and comprehensible classification rules from large databases. We emphasize predictive accuracy and comprehensibility of the rules. However, accuracy and comprehensibility of the rules often conflict with each other. This makes it an optimization problem that is very difficult to(More)
Wireless sensor networks (WSNs) are required to provide different levels of Quality of Services (QoS) based on the type of applications. Providing QoS support in wireless sensor networks is an emerging area of research. Due to resource constraints like processing power, memory, bandwidth and power sources in sensor networks, QoS support in WSNs is a(More)
This paper proposes a technique for dynamic slicing of UML architectural models. The presence of related information in diverse model parts (or fragments) makes dynamic slicing of Unified Modeling Language (UML) models a complex problem. We first extract all relevant information from a UML model specifying a software architecture into an intermediate(More)
