COMP20007 Design of Algorithms Divide-and-Conquer Algorithms Lars Kulik Lecture 9 Semester 1, 2021 1 Divide and Conquer We earlier saw recursion as a powerful problem solving technique. The divide-and-conquer strategy tries to make the most of this: 1. Divide the given problem instance into smaller instances. 2. Solve the smaller instances recursively. 3. Combine the

COMP20007 Design of Algorithms Graph Traversal Lars Kulik Lecture 7 Semester 1, 2021 1 Breadth-First and Depth-First Traversal There are two natural approaches to the traversal of a graph. Suppose we have a graph and we want to explore all its nodes systematically. Suppose we start from node v and v has neighbouring nodes x,
