I need to minimize a function that only allows integer input. Can I solve it with scipy.optimize.fmin? Otherwise, is there any alternative?

  • Did you find a solution? – SwimBikeRun Jul 17 '20 at 18:04

    Have some comments here that helped me. In my case, it was monotonically decreasing (no local minima), so a simple bracketing bisect worked fine and although it's not as fast as a potential solution from root finding analogs (would be interested if possible for the math theory aspect), it's still very very fast as the problem of finding a root at maximum precision isn't an issue. https://stackoverflow.com/questions/62959501/how-to-minimize-a-real-function-with-only-integer-input?noredirect=1#comment111338050_62959501 – SwimBikeRun Jul 20 '20 at 03:55
