A brilliant computer scientist who researched program correctness, mathematical methodologies, algorithms, and systems. In 1968 Dijkstra wrote a letter to an editor entitled "GO TO Statement Considered Harmful", (Comm. ACM, August 1968), and began the movement toward reliable software development. Or so they say. He is probably best known for his shortest path algorithm, used in such link-state algorithm .

"Dijkstra probably hates me."
