u Conventional algorithm had a potential problem, in that if the shape of function is asymmetrical, this previous method may miss the peaks having small niche radius.

u In order to find multi peaks accurately in solution space, both (right & left) niche radii of each elite should be determined differently and automatically according to its circumstance.

u E1 and E2 are elites, and R1_L and R1_R are left and right niche radius of El respectively, and R2_L and R2_R are left and right niche radius of E2
