A dragonfly is an insect belonging to the order Odonata, infraorder Anisoptera Adult dragonflies are characterized by large, multifaceted eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body.

蜻蜓算法（DA）作为一种新兴的元启发式智能算法，有较强的稳定性，较好的寻优速度及全局寻优能力等优点。(Dragonfly algorithm (DA) is a new meta heuristic intelligent algorithm has better stability, better searching speed and global searching ability.)

新型算法之蜻蜓优化算法，通过观察自然界中蜻蜓的动静态得之。(The new algorithm for dragonfly optimization is obtained by observing the movement and static state of dragonflies in nature.)
