This is the method I'm using and the fastest I know: set @count = (select count(*) from table); set @offset = convert(floor(rand() * @count), signed); prepare mystatement from "select sql_no_cache * from table limit ?, 1"; execute mystatement using @offset; deallocate prepare ...

A similar explanation applies to any divide-and-conquer algorithm; for example, MergeSort is another divide-and-conquer sorting algorithm, with the same intermediate tree shape, but this time with a simple splitting phase and all the comparisons in the recombining phase: (Choosing this particular...
(and IRAP; see below) brings with it even more unfortunate requirements to deal with the fallout from this noisy measure in ways that make the resulting test score even more opaque than we have outlined thus far. In particular, the widely used IAT-Dscore algorithm (Greenwald et al.,2003)...
We can see from the behavior of this algorithm that it can always find better solutions, but, when finding a new solution, the solution quality stays the same and does not change so much. This means that the algorithm is guided by the good solution (BV-vector) and also escapes from the...

The point of intersection can be determined by the algorithm: ro = P . oldpos rn = P . newpos Then the point of intersection is given by: ro rn Pi = --- Po + --- Pn (rn - ro) (rn - ro ) This can be rearranged to give: ro.Po + rn.Pn Pi = --- (rn - ro) where...
