Binomial heaps

The goal of this assignment is the implementation of a binomial HEAP data structure in Java using the provided skeleton classes which are provided together with several validation and unit test methods you can use to check your implementation. Skeleton code and unit tests There are five files of Java code provided of which you will need to edit three (four for bonus): 1. [login to view URL], contains the implementation of a tree node 2. [login to view URL], implements the sub-data structure binomial tree made up of tree nodes 3. [login to view URL], implements the actual binomial heap, eventually containing multiple binomial trees (when adding more than two elements) Please read the provided source code documentation/comments in order to understand what each method should do. The names of the methods have been chosen to stay closely to the terminology used in the theory articles and/or the existing theory material from the course. Afterwards run the unit tests to check your implementation. Don’t forget to check stack traces to find the actual source of validation errors and exceptions… Bonus objective This assignment has a single bonus objective worth 20 % of the overall mark: When looking up the second theory article you will find a big-O notation table comparing the various heap implementations. The second column is dedicated to binomial heaps. In order to fulfil the bonus objective you have to modify the code and add new unit tests to run sufficiently large enough numbers (choose at your own discretion). The goal is to verify the big-O and big-Theta values found using the measurement techniques discussed and applied during the course and first assignment. Be sure to add the necessary outputs to your test method to show the actual values and the expected (stick the current “n” into the formula found in the article and calculate). Example: If an operation has an expected big-O of n * ln n and the chosen n is 1000 the expected value is 6907.755. If your measurements result in a value minimum upper-bound by the example values (you will need to run multiple n values to verify the behaviour, a single value won’t suffice!) you verified the provided big-O.
