How can i create a loop that decreases all the values in a vector until a limit. i want find the optimal weight of a frame by decreasing the size of the metal until it breaks at a maximum force and there are 14 of them

Yeah

That would be more than 2^46 different possibilities. If you could process 5*10^7 possibilities per second (10^9 would not be realistic, 10^8 seems unlikely) then you would need 2*10^5 seconds, which would be more than 55 hours of computation. It would not surprise me at all of you cannot realistically get more than 10^6 computations per second using this approach, so I think several weeks of computation is more likely.

Are you certain this is wise considering the alteratives?

For example have you considered the possibility of using a minimizer program in which the quantity being optimized is the weight of the frame, and "breaking" is expressed through a nonlinear constraint?
