So, at 2:00 am last night I decided I had completed my 3-CNF-SAT algorithm (which runs in polynomial time!!). Well, here is the pseudocode: ROUTINE(P): -> Make a hashtable 'h' of size 3 * no. of clauses -> For clause p in P: for each 'distinct' variable x in p: h[x] += 1 -> Find […]

This semester I had the fortune of taking Dr. Greg Frederickson's CS 381 (Algorithms) class. And boy did I see weird stuff in there. Below, I have a list of analyses I say are downright the most non-obvious (and in a way beautiful to look at). Edmonds-Karp Algorithm (Max Flow in a network): This algorithm […]
