Talk:Fast marching method

Not the first
Sethian wasn't the first to introduce this. See:

http://www.mit.edu/~jnt/dijkstra.html

For the first guy to come up with this (that we know of). Another fellow also beat Sethian to the punch. There are much testimony by researchers in this area that attest to Sethian not being the first, and in fact folks like Stan Osher claim that Sethian knowingly stole the idea and took credit for it.
