In England the currency is made up of pound, £, and pence, p, and there are eight coins in general circulation: 1p, 2p, 5p, 10p, 20p, 50p, £1 (100p) and £2 (200p). It is possible to make £2 in the following way: 1x£1 + 1x50p + 2x20p + 1x5p + 1x2p + 3x1p How many different ways can £2 be made using any number of coins?

A generalised version of the solution to the fourth Project Euler problem - Largest palindrome product, using sequences. The key to understanding this code is how "Seq.map (fun x -> (Seq.map (fun y -> x * y) baseSeq)) baseSeq" generates a sequence of sequences that contains the products of all possible combinations of two n-digit numbers. "Seq.map (fun x -> (Seq.map (fun y -> x * y) {1..3})) {1..3}" will generate: seq [seq [1; 2; 3]; seq [2; 4; 6]; seq [3; 6; 9]]

Generating a state space tree to the Missionaries and Cannibals Problem (http://en.wikipedia.org/wiki/Missionaries_and_cannibals_problem). Then, this tree is iterated with depth-first approach, printing all the visitations. The solutions to problem have a depth equals 9.
