Problem 3. (Operator Norms.) In Mod3-L2 we saw the concept of an operator norm:
|| Ax ||p
|| A||,
= max ||Ax ||p.
||2||=1
= max
In lecture we saw that
m
||4||1
max ||Ax1
||x||1=1
max
j=1,...,n
i=1
> Jaij i.e., the max column sum
where ||x||1 =E; ai|. Show that this equality holds. That is, show that ||A||1 is in fact the max
column sum.
c) Knowing that we have the equality:
12Ar+3= B2hez
determine the value of x and encircle it.

A group of n people are lying on the beach. The beach is represented by the real line R and the location of the i-th person is some integer r; e Z. Your task is to prevent people from getting sunburned by covering them with umbrellas. Each umbrella corresponds to a closed interval I = [a, a + L] of length L e N, and the i-th person is covered by that umbrella if æ¡ € I. Design a greedy algorithm for covering all people with the minimum number of umbrellas. The input consists of the integers x1,..., En, and L. The output of your algorithm should be the positions of umbrellas. For example, if the input is r1 = 1, x2 = 3, r3 = 5, and L = 2, then an optimum solution is the set of two umbrellas placed at positions 2 and 5, covering intervals [1,3] and [4,6]. 1 2 3 4 5 6 Prove that your algorithm is correct and that it runs in time polynomial in n.arrow_forward
