I assumed that we always had to use the most previous value when determining the next.
3*3 = 9, you're allowed to use any combination of previous values to get the next one.
Is it really linear if we aren't forced to use the previous value?

No, the article I referred to in the original post was talking about a different aspect of straight line programs.
question: is division ever faster? the opening post mentioned that it affects the problem, but i think multiplication, addition and subtraction are enough to get any minimum number of steps. I'm not sure if even subtraction is necessary.

311 for some time, and I can't do it with an 8-long program (including
the first 1). But eventually I got a 9-long which ended in 311. Can
you guys do it in an 8-long, like you did with the previous numbers?

Nice, but do you have any reason to believe there is no 8-long?Spoiler for pretty sure its 9 long.
If you look at the end of my 9-long, you'll see that it ends in what
are almost "wasted" moves:
