The algorithm utilizes a variable-length coding structure to represent the solutions of VMMOPs and incorporates a dimensionality incremental learning strategy to generate representative solutions for training two learning models. Experimental results demonstrate the effectiveness and competitiveness of the proposed method in handling VMMOPs.
