Dynamic Programming (a) Find the grouping of the matrices that will minimize the number of operations to compute A1*A2*A3*A4. The sizes of the matrices are as follows; А1-2х1; А2—1x5; АЗ—5х2; А4-2х2 you just show the steps without the computations you get 4 points; you make errors in calculation you get 4 to 9 points. Completely correct answer is 10 points. (b) For the problems given below, determine whether it is more efficient to use a divide and conquer strategy or a dynamic programming strategy. Give the recursion formula for each. 4. If If i. Find the average of a given set of unsorted numbers. ii. Find whether there is a subset of integers in a given set that adds upto 8 iii. Given a set of numbers, can they set be partitioned into two groups such that the sum of each group is equal; i.e 1,5,11,5 can be partitioned to 1,5,5 and 11 (c) State the difference between divide and conquer and dynamic pro- gramming.
