I have selected an non-negative integer (with no upper bound on the integer I may have selected). When you guess what it is, you will be told whether you guess is correct, higher than my number, or lower than my number, and then you may guess again. Do you have an optimal strategy to correctly guess my number in as few guesses as possible?
I have a hypothesis of a strategy but I don’t know if it’s actually ideal.

Hi #Mathstodon - a #GraphTheory question:
Given the following visual set containment, I can obtain the total containment of every item as a list (text on the left). This intuitively seems sufficient information to derive the containment graph (almost a tree - n7 breaks that).
Are there any 'standard' techniques to apply to this?
Boosts, partial ideas, discussion all welcome.
