BAN USERHere is an excerpt from wikipedia's entry on "greedy algorithms":
Greedy algorithms mostly (but not always) fail to find the globally optimal solution, because they usually do not operate exhaustively on all the data. They can make commitments to certain choices too early which prevent them from finding the best overall solution later. Nevertheless, they are useful because they are quick to think up and often give good approximations to the optimum.
If a greedy algorithm can be proven to yield the global optimum for a given problem class, it typically becomes the method of choice because it is faster than other optimisation methods like dynamic programming. Examples of such greedy algorithms are Kruskal's algorithm and Prim's algorithm for finding minimum spanning trees, Dijkstra's algorithm for finding single-source shortest paths, and the algorithm for finding optimum Huffman trees.
It depends on whether you want an efficient solution that works most of the time or a solution that's less efficient but works all of the time. Dijkstra's algorithm is a "greedy algorithm" and thus doesn't work 100% of the time.
I'm thinking something like a recursive solution, where at each vertex you traverse to each of the immediate neighbors, returning the shortest path at each level. Of course, you have to keep track of the visited vertices so as to not get into any loops.

In fact, could the "one"s and "two"s be garbled? The child processes could be operating on separate cores and the prints could be happening simultaneously, right? (or even if they were on just one core, can a process be preempted in the middle of a printf?)
