E, \y4|. Given any particular A E RXn and b E R", consider the problem min ||Ax b||1 s.t. x > 0, where x E R" For any y E R", we define its 1-norm as y||1 := 3D1 - are variables. Express as an equivalent linear programming problem min c'x s.t. Ax = b, x > 0. (In other words, write the matrices/vectors A, b, c.)
