Neurophysiologic achievements claimed that the fly visual system could naturally contribute to a type of artificial computation model which used motion‐sensitive neurons to detect the local movement direction changes of moving objects. It, however, still remains open how the neurons' information‐processing mechanisms and the inspirations of swarm intelligence can be integrated to serve an interdisciplinary topic between computer vision and intelligence optimization‐visual evolutionary neural networks. Hereby, a fly visual evolutionary neural network is developed to solve large‐scale global optimization (LSGO), inspired by swarm evolution and the characteristics of fly visual perception. It includes two functional modules, of which one is to generate global and local motion direction activities of visual neural nodes, and the other takes the activities as learning rates to update the nodes' states by a population‐like evolutionary strategy. Also, it is used to optimize the structure of a multilayer perceptron to acquire a sample classification model. The theoretical results indicate that the network is convergent and meanwhile the computational complexity mainly depends on the size of the input layer and the dimension of LSGO. The comparative experiments have verified that the network is an extremely competitive optimizer for LSGO problems.
