Why Bee colony is the most suitable with multi-query optimization?

This paper presents the comparison results on the performance of the swarm algorithms with Multi-Query Optimization (MQO). First the paper discusses query optimization process and the challenges appear when applied on multi query. Then the paper tackles swarm algorithms and how did they confront these challenges and achieve good results. Finally, proved that Artificial Bee Colony (ABC) algorithm achieves the best results in time and performance.
