@user10478 It's essentially an index, so that you can have several integration constants/summation indices.

Do we have any meta threads about how (not to) write a question?

If I have an arbitrary function f[x_Integer] that returns a number (in this case doing some geographic stuff with areas - NOT an algebraic thing I could mathematically simplify), what function do I use to automatically bisect to find the minimum number efficiently? I end up just doing it manually because I don't really understand how NMinimize etc work.

Buy Audiobook One year ago I released my book The Math(s) Fix: An Education Blueprint for the AI Age. It’s been great to have seen it so well received in the media—featured in Forbes, The Guardian, The Wall Street Journal and even winning the 2021 Independent Press Award for Education—as well as praised by individuals […]

@CarlLange Can you just do NMinimize[f[x], x\[Element]Integers]?

@b3m2a1 I think I did try this, but didn't have the syntax right. I'll give it another go tomorrow. Thanks!
 
Silly question: How does one format code snippets in Comments in SE? i.e., the little gray boxes around x=2.

@CraigCarter Wrap in single backticks
 
thx!
 
You're welcome :)
 
@MichaelE2 Just gave you credit for an older post (mathematica.stackexchange.com/questions/249975/…). I couldn't figure out a way to clear downvalues properly. Found your nice answer.
 
@CraigCarter Thanks!

@CarlLange I think FindMinimum[..., {xStart,xMin,xMax}] uses bisection starting at xStart?
Not quite bisection: `Reap[FindMinimum[x - Sqrt[x], {x, 11, 0, 12},
EvaluationMonitor :> Sow[x]]]`

Completely off topic: I'm gonna be on national TV tomorrow! Here's hoping I don't just swear nonstop 🤞
