Thanks for the questions!!

'Does some AI simply need to be able to win the game of Hanabi with higher probability than a group of human players?' Hanabi does not have winners and losers it is a group game where you need to infer values through the actions of others to make a judgment.

' How would this be determined?'

It would be the current records of top professionals and if they are surpassed.

' What is the motivation for the human players to play optimally?'

They are have been competing for a long time and there is a lot of data for the teams to compare against.

'If this isn't tested before the resolution date, does it resolve as N/A or NO? '

Nieves Montes, Ph.D. and colleges are trying to crack it right now and if they don't, by that date, it resolves as a NO.

What exactly are the resolution criteria here? Does some AI simply need to be able to win the game of Hanabi with higher probability than a group of human players? How would this be determined? Having the AI play a certain number of games, and having a group of human players play the same number of games? If so, which human players? For example, would a random group of players be chosen, or would a prior instance of top professionals playing a given number of games be retroactively chosen as the benchmark? What is the motivation for the human players to play optimally? If this isn't tested before the resolution date, does it resolve as N/A or NO?
