The more interesting question is which houdini does not use that formula because there are more than one houdini version.

If you're really interested, no version of Houdini has used the formulae that Marco quoted above.
Houdini uses an aspiration window that widens much faster.

Thanks Robert.

My intuition also tells me that it is better to have less researches(increasing delta faster by a different formula may be a way to do it)

Maybe the stockfish team may try something like

if (bestValue >= beta)
{
beta += delta;
delta += delta*2;
}
else if (bestValue <= alpha)
{
alpha -= delta;
delta += delta *2;
}
