BFS and DFS - know their computational complexity, their tradeoffs, and how to implement them in real code When asked a question, look for a graph-based solution first, then move on if none. MIT(videos): Breadth-First Search Depth-First Search Skiena Lectures - great intro: CSE373 2012 ...
Greedy Algorithms are algorithms that make locally optimal choices at each step in the hope of eventually reaching the globally optimal solution Problems must exhibit two properties in order to implement a Greedy solution: Optimal Substructure An optimal solution to the problem contains optimal solutio...
