1. Apply the Apriori Algorithm Tasks: Apply the Apriori Algorithm to the following data set: Trans ID Items Purchased 101 milk, bread, eggs 102 milk, juice 103 juice, butter 104 milk, bread, eggs 105 coffee, eggs 106 coffee 107 coffee, juice 108 milk, bread, cookies, eggs 109 cookies, butter 110 milk, bread The set of items is {milk, bread, cookies, eggs, butter, coffee, juice). Use 2 for the minimum support value. You must show all candidate and large itemsets during the process: C., L, C2, L2 etc. until the algorithm terminates.

Q2. In a retail store following sales transactions took place: Sales_ID Items S1 {O,W,C,N,Z} S2 {O,C,K,N,Z} S3 {K,N,W,Z,O} S4 {K,W,Z,O} S5 {C,K,N,Z} S6 {O,K,N} S7 {O,N,W,Z} S8 {K,N,Z} Find frequent itemsets and association rules using Apriori Algorithm. The minimum support is 0.4 (threshold) and minimum confidence is 0.9.

Given a directed graph with non-negative integer edge weights, a pair of vertices s and t, and integers K and W, describe a dynamic-programming algorithm for deciding whether there exists a path from s to t that has total weight W and uses exactly K edges. Your algorithm should run in time O(nm)WK). Analyze the time- and space-complexity of your...
