The problem above is called the Two Generals Problem, and it’s provably unsolvable. If we remove the condition that both generals must be 100% confident that the other one will attack, we can still change a few things. In the new version of the problem, Alice is the leader, she decides when to attack, and she will attack no matter what Bob says.
