...is preferred.
As a general rule, I prefer to keep the database's job to a minimum "store this data, fetch this data" - however, there are always examples of scenarios where an elegant query at the server can save a lot of bandwidth.
Also consider: if this is computationally expensive, can it be ca...

Has anyone actually implemented a Fibonacci-Heap efficiently?
... intrinsically decrease_key-intense; I wanted to try the Nagomochi-Ibaraki minimum-cut algorithm because apparently it generates lots of decrease_keys, but it was too much effort to get a timing comparison working.

Knight's Shortest Path on Chessboard
... you draw the board. In the diagram below, the number in the square is the minimum number of moves needed to reach that square (you can use breadth-first search to find this):

If it still seems fair or we haven't reached a threshold of minimum rolls, it returns a fair hit based on the normal probability.
If the observed probability from past rolls makes it seem unfair, it returns a "fair-ifying" hit.
