In this paper, a variant of particle swarm optimization (PSO) is presented to handle the problem of stagnation encounters in PSO which may lead to get it trapped in local optima and premature convergence particularly in multimodal problems. The proposed scheme Dynamic-PSO (DPSO) does not disturb the fast convergence characteristics of PSO by keeping the basic concept of PSO unaffected. When particles...
Researchers have proposed that the reliability of software prediction models can be assessed by the following most widely used evaluation criterion, i.e., Difference Measure and Ratio Measure. Ratio measure is more suitable for the assessment of the accuracy in software cost estimation. Results in this research demonstrated that applying proposed method to the software effort estimation is by far...
In this paper, a variant of particle swarm optimization (PSO) algorithm using modified time varying acceleration coefficients (PSO-TVAC) has been proposed and applied in creation of new test cases for modified code in regression testing. The performance of the proposed algorithm is compared with other existing PSO algorithms on five well known benchmark test functions. The experiments prove that the...
Most of the proposed works in Routing protocol for hybrid wireless mesh networks are based on AODV. To be more effective in hybrid wireless mesh networks, the enhancement of AODV is very much important. In this paper, we propose a novel mechanism for route discovery and route repairing by exploiting local connectivity. In this approach, any neighbor node of the destination node can provide a route...
In maintenance, regression testing is used to revalidate modified software which is also an expensive and frequently executed process. In conventional regression testing approach, developers generally re-run all test suite or selectively run a sub-set of existing test cases on the modified version of program. After executing the test cases over program, developer may reveal the regression faults due...
All areas relating to telecommunications, electricity distribution, and gas pipeline require Topological optimization. It also has a major importance in the computer communication industry, when considering network reliability. In this paper, we have used GA with specialized encoding, initialization, local search operators with specially designed crossover operator called alternating crossover [21]...
Many real life problems require optimization of more than one objective functions, these problems are known as multi-objective optimization problems. Although many algorithms are available in literature to solve these types of problems [2, 3, 4, 5, 21] but they treat every objective function equally. Sometimes, on the basis of problem to be optimized, different objective functions can be assigned...
Load balancing in distributed computing environment enhances the availability and scalability of entire system. The computational paradigm has shifted dramatically from standalone computing, C/S computing, distributed computing to cluster computing paradigm. Although numerous works has been done on the issue of process migration and load balancing, a comprehensive approach still misses out on various...
The current business environment has become still more demanding in which organizations are under increasing pressure not only to increase revenue but also to respond quickly to changing market conditions. These organizations shall only be successful if they transform themselves and adapt on demand businesses paradigm. There is constant demand for innovation and shorter time to market for products...
With the growth of IT and software industry there has been a shift in the software development paradigm from traditional techniques based to object-oriented and component-based development techniques. Due to this shift dynamic changes occur in the technology, environment and many other qualitative/quantitative factors, leading to increased maintenance effort. The challenge then lies inaccurately modeling...
The basic principle in designing digital circuit hovers around reducing the required hardware thus reducing the cost too. To achieve this, we use Boolean expression that helps in obtaining minimum number of terms and does not contain any redundant pairs. The conventional methods for the minimization of the Boolean expressions are K-Map method and the . The minimized expressions are used to design...
Agent oriented software development is generally motivated by the need of open and adaptive systems development that continuously change and evolve to meet new requirements. In this paper, we propose model-based technique that provides a specific model for the type of information to be gathered and uses this model to drive the domain specific analysis process. In the proposed agent-based system, the...
This paper makes an attempt to propose cognitive software development model and demonstrate that the software development lifecycle should also be constrained by the laws of cognitive informatics. An attempt has also been made to frame cognitive complexity metrics for all the phases of cognitive software development process
An agent-based system is a complex software system with functional and non-functional requirements. Non-functional requirements (NFRs) are crucial software requirements that have been specified early in the software development process while eliciting the functional requirements (FRs) in agent oriented software development. Some of the functional and non-functional attributes are of a crosscutting...

In this paper, we propose an agent-based open and adaptive system development process. The proposed methodology is based on model-based techniques and provides a specific model for the type of information to be gathered and uses...
In this paper, an attempt has been made to evaluate cognitive information complexity measure (CICM) terms of nine Weyuker properties. It has been found that all the nine properties have been satisfied by CICM and hence establishes cognitive information complexity measure based on information contained in the software as a robust and well-structured one
It is shown how, by augumenting a microprocessor or mincomputer with a relatively small amount of iteratively driven logic, the operation of table lookup using a binary search algorithm can be speeded up by 1?? to 2 orders of magnitude. The approach is very suitable for 1.s.i. implementation as a standard peripheral device for a microprocessor.
