comment Least number of inspections to find a given card
@rraallvv Can you give me some hints about the 'little room'? I thought about this for 2-3 months, but I can't find a solution better than m = 49.

@rraallvv Thanks, but I want a better solution than $m = 49$.

@rraallvv Player A opens all the box, so the player can see the form of the cycle. Then, the player will switch two cards which minimizes the maximum length of the cycle.

My algorithm and your algorithm looks the same. I think there must be a better solution, but I can't find it.

um.. is there more faster solution than just substracting?

@Hurkyl I'm not sure that it's okay to solve n x m equations.
