Given A = {a_1,…,a_n}, the response y, and a set of edges E, this function aims to solves
min 1/2||Ax-y||^2 + λ_1||x||_1 + λ_2 ∑_{(i,j) in E}w_(i,j)|x_i-r_(i,j)x_j|
where w_(i,j) is the weight of the edge (i,j), and r_(i,j) is the sign of the correlation between features a_i and a_j. The weight and sign can be specified in Rwt: w=|Rwt|, and r=sign(Rwt).
