One clip per environment from this entry's evaluation, beside where each evaluation episode placed the environment's objects, coloured by its rating; a placement several episodes shared is drawn once, in their ratings' colours mixed. Use the button beside each environment to open its evaluation dataset in the dataset viewer. One episode is available to watch; the remaining episodes can be requested in case of a dispute or for another legitimate reason.
