Freeform metasurfaces based on topology optimization enable precise control over electromagnetic functionalities, with widespread applications in metagratings, metalenses, and polarization transformations. The selection of the initial structure plays a crucial role determining quality final results. In this study, global solution-based (GISTO) is proposed to design beam merging metagrating efficiently. A two-dimensional encoded non-dominated sorting genetic algorithm II employed for exploration obtain high-quality structure, which then refined using gradient-based local design. By integrating optimization, efficiency significantly improved. Under symmetric incidence, efficiencies x-polarized y-polarized beams reach 93.6% 95.3%, respectively, while under asymmetric achieve 99.4% 95.4%, respectively.
