回複：回複：there is a solution

for envy-free cake cutting, bounded discrete procedures are only know for <= 3 people. for 4+ people, there are moving-knife procedures but they are fundamentally different from discrete procedures. so bounded discrete procedure for 4 people is still open. I used to work on this problem a bit, and I thought such procedure does not exist.
