Monthly runoff time series prediction by variational mode decomposition and support vector machine based on quantum-behaved particle swarm optimization
TL;DR: Wang et al. as mentioned in this paper developed a hybrid model for monthly runoff prediction, where observed runoff is decomposed into several subcomponents via variational mode decomposition, and support vector machine models based on quantum-behaved particle swarm optimization are adopted to identify the input-output relationships hidden in each subcomponent.

Dispersed foraging slime mould algorithm: Continuous and binary variants for global optimization and wrapper-based feature selection
Jiao Hu,Wenyong Gui,Ali Asghar Heidari,Ali Asghar Heidari,Zhennao Cai,Guoxi Liang,Huiling Chen,Zhifang Pan +7 more
TL;DR: In this article, a swarm-based stochastic optimizer with a dispersed foraging strategy is proposed to enhance the slime mold algorithm and maintain population diversity, and the experimental results reveal that the BDFSMA performs better than the original SMA, and that, compared with other optimization algorithms, it improves classification accuracy and reduces the number of selected features.
