Comparison of Hash Table Performance with Open Addressing and Closed Addressing: An Empirical Study [PDF]
International Journal of Networked and Distributed Computing (IJNDC), 2015 In this paper, we conducted empirical experiments to study the performance of hashing with a large set of data and compared the results of different collision approaches. The experiment results leaned more to closed addressing than to open addressing and
