(A) Ten networks of 10 genes {A,B,C,D,E,F,G,H,I,J}, where the edge weight is associated with the color scale shown in (C); (B) The optimal membership vectors

. Three RHSs are discovered: the first RHS recurs in networks {1,2,3,4,5,6,7} with member genes {A,B,C}; the second recurs in networks {1,2,3,4,5} with member genes {A,B,C,D,E}; and the third recurs in networks {1,2,3} with member genes {A,B,C,D,E,F,G}; (D) A more intuitive illustration of three three overlapping RHSs, which form a tower-like structure.
