A new algorithm for iterative optimization of wavefront shaping which is the combination of Nondominated Sorting Genetic Algorithm Ⅱ-Hybrid and the superpixel method is proposed， using digital micromirror devices for light field modulation. Multi-point controllable light focusing of reflective wavefront shaping is realized. Our method has two advantages. On the one hand， while increasing the enhancement factor， it also ensures that the uniformity of the intensity of multiple focal points is controllable， that is， all focal points have uniform intensity； on the other hand， the structure of reflective wavefront shaping is more conducive to application. In order to verify our algorithm， we use frosted glass as the scattering media in the experiment. The experimental results show that， compared with the genetic algorithm based on superpixel method， the enhancement factor of the focal point is increased by 24.12%， and the coefficient of variation is reduced from 13.3% to 4.2%. This research provides a new method for reflective wavefront shaping multi-point light focusing， and has potential application value in the field of optogenetics and light capture.
