TITLE: Nature-Inspired Algorithms: Promise and Prejudice SPEAKER: Xin-She Yang ABSTRACT Nature-inspired metaheuristic algorithms such as particle swarm optimization and firefly algorithm have become very popular in optimization and computational intelligence in recent years. However, confusion, distraction and prejudice in the literature may have caused some resistance. We will discuss the advantages and disadvantages of metaheuristic algorithms by analyzing some algorithms. We will also discuss open problems and further research topics.
