algorithm

I need dynamic dijkstra algorithm that can update itself when edge's cost is changed without a full recalculation. Full recalculation is not an option.
I've tryed to "brew" my own implemantion with no success. I've also tryed to find on the Internet but found nothing.
A link to an article explaining the algorithm or even it's name will be good.

Edit:
Thanks everyone for answering. I managed to make algorithm of my own that runs in O(V+E) time, if anyone wishes to know the algorithm just say so and I will post it.
