The algorithmic approach to solving problems in computer technology is an essential tool. With this unique book, algorithm expert Roland Backhouse shares his four decades of experience to teach the fundamental principles of using algorithms to solve problems. Algorithmic Problem Solving studies the implementation and application of Students who would like to develop their programming and algorithmic skills by. Invariant” means “not changing”. An invariant of some process is some attribute or property of the process that does not change. Other names for “invariant” are.

Run Dijkstra on the graph of elevator,floor pairs. The queue is initialized with all pairs of the form e,0 where elevator e can go to floor 0. Remember that switching elevators requires 60 seconds.

Use Bellman Ford and note that the edge weights are the differences in busyness cubed.

Correction to problem statement: There may be multiple blank lines between each input test case. To address this, and any other weirdness, make the first line of your main while loop start with: After running all pairs shortest path, the answer can be computed quickly.

For each connected component, count the number of odd degree nodes, and use what we learned algorithmic problem solving Eulerian graphs.

Just count the number of paths using memoization. Slightly trickier Bellman Ford.


Don't reallocate any data structures unnecessarily, or use any hashing. Programming Homework 8 graded out of 5.

Just implement Euclid's algorithm. Use a stack to evaluate the reverse polish notation. As numbers can get big, use longs and mod by N after every computation. Max flow on a bipartite graph with an added source and algorithmic problem solving.

Algorithmic Problem Solving

Max flow on a bipartite graph where you need to output your solution. Can just look at neighbors of each category node to build output.


Min cut with vertex and edge capacities. Even though the graph in the problem is undirected, your graph should be directed to properly handle the vertex capacities.

CHAPTER 2: Invariants - Algorithmic Problem Solving [Book]

Programming Homework 9 graded out of 6. You can compute the probability using binomial coefficients, algorithmic problem solving can look up the negative binomial distribution, and I think even Markov chain techniques will work.

Make sure to use doubles for all of your calculations.
