Augmented Treap Background An augmented data structure (like an augmented treap or an interval tree) is built upon an underlying data structure. New information (data) is added which: – Is easily maintained and modified by the existing operations of the underlying data structure and – Is used to efficiently support new operations. Process of augmenting […]

R-Way Trie de la Briandais (1959) and Fredkin (1960) Introduction › An r-way trie (retrieval) is an alternate way to implement a hash table. Therefore, items are inserted, removed, and retrieved from the trie based on pairs. › Each successive character of the key such as: – a digit where the key is a number

Treap Cecilia Aragon and Raimund Seidel, 1989 Background › A treap is a randomly built binary search tree › The expected time complexity to insert and remove an item from the treap is O(log n) › Inspired as a combination of a binary search tree and a binary heap (hence, treap) Review › Property of

B-Trees (Chapter 18) Bayer and McCreight (1972) What does the “B” stand for? Background › A B-tree is a balanced search tree which is used to store the keys to large file and database systems › Because: – only a part of a B-tree can be stored in primary (main) memory at a time and

Depth-First Search Overview › Depth-first and breadth-first (next section) searches are two classic and diametrically opposed ways to systematically process the vertices of a graph Depth-first strategy › Let V be an initially empty set of visited vertices › Process and place the starting vertex s in V › The next (unvisited) vertex to process

COMP9312_Project_Q1: Computing Shortest Distance¶ For details about the project, please refer to the project specification. You can edit this file and add anything you like. We will only use the code cell of ShortestDistance class for testing. Instead of creating a seperated PDF document, you can add descriptions and some theoretical analysis (e.g., index space,

CSCI-1200 Data Structures — Spring 2021 Homework 6 — Crossword Blackout In this homework we will work with concepts inspired by crosswords, however we will not be following all the rules that would be required by a proper “American-style” or “British-style” crossword. As such, you should read the entire handout carefully. Crosswords are quite popular,
Project 1 Verification Condition Generator Write a Verification Condition Generator (VCG) for our simple imperative language, IMP, using the parser generator ANTLR. Use the Weakest (Liberal) Precondition Predicate Transformer semantics. This allows you to use backward substitution over if-statements. For while-loops, simply print intermediate verification conditions instead of combining them into a single verification condition
