- Collection of hundreds more Ad Hoc problems with hints to kick start your training programme
- More contest-related exercises :)
- More persuasive writing that the world of competitive programming is fun
- More balanced viewpoint: C++ vs Java, ICPC vs IOI
- Lots of footnotes in the second edition that gives more insights on the stuffs being discussed in the body text

- NEW in 2011: Discussion of lightweight set of Boolean (bitmask technique). This technique is important for competitive programmers and will be used several times in various sections of this book
- NEW in 2011: Short discussion on implicit graph
- NEW in 2011: Fenwick Tree (Binary Indexed Tree), uses bit manipulation
- More conceptual exercises

- More speed up tips to improve your solution, (especially the brute force solution)
- More Divide and Conquer examples, clearer explanation of 'Binary Search the Answer' technique
- More Greedy example: interval covering problem
- Clearer explanation of DP technique: the steps required to come up with a DP solution, especially the bottom-up version
- Reconstructing the optimal DP solution
- O(n log k) solution for LIS problem
- 0-1 Knapsack/Subset Sum
- DP TSP (bitmask technique again)

- Reorganization of graph sections (more reader friendly now)

- Training to identify the flow graph of a problem solvable with max flow
- DP as a traversal of (implicit) DAG
- One more special graph: Eulerian Graph
- Augmenting Path Bipartite Matching algorithm
- A chapter with lots of short profiles of algorithm inventors (new feature of this book)

- Much more mathematics problems

- More discussion on Floyd's cycle finding algorithm
- NEW in 2011: Game Theory
- NEW in 2011: Powers of a (Square) Matrix, can be applied to DP too

- Basic string processing skills (new section)

- More advanced DP: bitmask technique, compilation of common DP states, better state representation, etc

- Steven's Methods to Solve is now integrated in the second edition
- 1198 UVa problems are listed, 600 more than the 1st edition. Getting more than 1000 problems AC is no longer a wild dream
