Problem 2.2 : Given a point xo ER, the shrink function is defined as the unique solution to the following optimization problem: 1 shrink(xo) arg min |w| +=(x xo)2. XER Suppose that y* = (y1, y ) is the unique solution to the con-strained optimization problem 1 min y2 + +(y1 - x0)2 such that y2 > 41, 42 > -41. Y1,42 Explain why yi = shrink(xo).
