CE204 Data Structures and Algorithms Part 4 09/02/2019 CC204 Part 4 1 Analysing Running Times 1 If there are several possible algorithms for solving a problem we may wish to determine which is the most efficient. One way to do this would be to implement all of the algorithms and perform experiments. This may, however, […]

CE204 Data Structures and Algorithms Part 1 16/01/2019 CE204 Part 1 1 Recommended Reading The most useful book for much of the material in this module is Data Structures and Algorithm Analysis in Java (2nd ed.), M.A. Weiss (Pearson, 2007) This book does not, however, cover in detail all of the Java programming material. Hence

CE204 Data Structures and Algorithms Part 8 08/03/2020 CE204 Part 8 1 Balancing Binary Search Trees 1 We saw in part 4 that the average times for binary search tree operations are O(log n), but in the worst case the times are O(n). To obtain optimum performance we would like to ensure that binary search
