Generally, inaccurate estimation cost due to lack of data and inherent relationship between attributes. For accurate software cost estimation, the amount of techniques has been proposed, one of them is Particle Swarm Optimization (PSO) has been exposed an impressive performance. However, it is struck at local minima due to    diversity loss quickly. In order to improve its searching ability and convergence rate, this paper proposes a new hybrid approach iscalled DPSONS-K. It consists a diversity enhanced method and neighborhood search methods with k radius. Where k is tuning parameter used to achieve stability between searching and convergence abilities.Seven benchmark datasets are used to investigate outcome of proposed approach.Comparative study shows that DPSONS-k approach achieved better results than other ones.</p>}, number={1s}, journal={International Journal of Intelligent Systems and Applications in Engineering}, author={Venkataiah, V. and Nagaratna, M. and Mohanty, Ramakanta}, year={2022}, month={Oct.}, pages={348–362} }
