A dandelion algorithm(DA) is.a recently developed intelligent optimization algorithm for function optimization problems. Many of its.parameters.need to be s.t by experience in DA,which might not be appropriate for all optimization problems. A s.lf-adapting and efficient dandelion algorithm is.propos.d in this.work to lower the number of DA's.parameters.and s.mplify DA's.s.ructure. Only the normal s.wing operator is.retained;while the other operators.are dis.arded. An adaptive s.eding radius.s.rategy is.des.gned for the core dandelion. The res.lts.s.ow that the propos.d algorithm achieves.better performance on the s.andard tes. functions.with les. time cons.mption than its.competitive peers. In addition, the propos.d algorithm is.applied to feature s.lection for credit card fraud detection(CCFD), and the res.lts.indicate that it can obtain higher clas.ification and detection performance than the-s.ate-of-the-art methods.
