why do two pairs of experiments make the same items? how can I keep track of likelihood of overlap for both pairs of experiments? how to predict the likelihood of overlap in the pair of experiments how to find out the likelihood of overlap for a pair of experiments if two experiments produce the same or similar set of items, is the winning item of both experiments the same what makes it possible for the experiment to produce identical item sets? how to keep track of the likelihood of overlap for both experiments how to keep track of the likelihood of overlap what makes a pair of experiments likely to produce the exact same set of items can an experiment produce the same set of items as the other experiment? when two experimental pairs produce a different set of items, the winner of each is how to track the likelihood of overlapping in two experiments how to predict if two experiments produce the same sets of items? what is the bandit in multiarm testing how to find the payoff of multiple experiments why is it possible for two pairs of experiments to produce the same item set? how can you calculate probability of overlap for pairs of experiments why is it a good idea to do a pair of experiments how do you get the highest cost for an experiment with the same payoff why does it need a bandit for an experiment
