Rank aggregation is an essential approach for aggregating the preferences of multiple agents. One rule of particular interest is the Kemeny rule, which maximises the number of pairwise agreements between the final ranking and the existing rankings. However, Kemeny rankings are NP-hard to compute. This has resulted in the development of various algorithms. Fortunately, NP-hardness may not reflect the difficulty of solving problems that arise in practice. As a result, we aim to demonstrate that the Kemeny consensus can be computed efficiently when aggregating different rankings in real case. In this paper, we extend a dynamic programming algorithm originally for Kemeny scores. We also provide details on the implementation of the algorithm. Finally, we present results obtained from an empirical comparison of our algorithm and two other popular algorithms based on real world and randomly generated problem instances. Experimental results show the usefulness and efficiency of the algorithm in practical settings.
