Why does Dijkstra's algorithm use decrease-key?
...nsert version. See http://www.cs.utexas.edu/users/shaikat/papers/TR-07-54.pdf
Their basic conclusion was not to use the decrease-key for most graphs. Especially for sparse graphs, the non-decrease key is significantly faster than the decrease-key version. See the paper for more details.
