Maybe Smallest Mouse

[tog]

good news: this can be solved in 23 instructions, i just realized (by looking at tog's very clever solution), so a brute force is a degree easier =)

Well, even better news: this can be solved in 21 instructions!
So may I suggest another challenge named "Smaller than the smallestest mouse"? Does this count as submission for "Create a Challenge"?

21! wow. yes, that will give you creation credit =)

This makes the hello world one look easy, mine was like 110 long.

[m!nus]

omg, no more! i guess i'll have to try again on that challenge

ok,ok I confess: my small mouse was cheating -- but only a little bit. It mostly finds the right solution and needs only 22 opcodes.

And cheating is a good qualification for hackers, isn't it?

how can you make it not always gets the right solution, do you ignore the last memory cell or something alike?

Just let me clarify things:
Does this (21) solution work on all possible inputs or is just able to pass the tests?

OH, finally I have rearranged my code and thanks to post solution forum I know 24 solution working for all inputs and 21 solution working with probability 1. (My 21 solution had probability 0.975).

But ... this is not over yet .
