Working on a problem. Making the computer do what it's doing faster is possible, but only a small change. I need to work out how to make it do less for the same results. Tricky.

Reminds of a code comparison between C and RUST where they have to calculate the summation of numbers from 1 to a big number.
C doesn't do any fancy stuffs and iterates the million times while RUST uses the sneaky formula of computing summation to do it 1800 times faster then C
@ColinTheMathmo
Mostly shortcuts are for specific conditions and stuffs, getting a generalised faster solution is sometimes not feasible.
@mur2501 In this case I'm doing a search, and I'm sure there are many shortcuts, but each shortcut I think about, I then can find a way it might go wrong.
Tricky.
