An Introduction to the Longest Increasing Subsequence Problem. The basic idea must be that whenever we branch into the car or the cdr (tree recurse) we equip the search with a "history" of all nodes visited from the root to the nodes we are moving to so that at any point a cycle (a traversal into a node in the history) can be dettected.
