Abstract
A computer-implemented method of evaluating the performance of a target planner for an ego robot comprises receiving evaluation data for evaluating the performance of the target planner in the scenario, generated by applying the target planner at incrementing planning steps, to compute a series of ego plans that respond to changes in the scenario and are implemented in the scenario to cause changes in an ego state. The evaluation data includes the ego plan computed by the target planner at one of the planning steps, and a scenario state at a time instant of the scenario. The evaluation data is used to evaluate the target planner by computing a reference plan for said time instant based on the scenario state, the scenario state including the ego state at that time instant, and computing at least one evaluation score for comparing the ego plan with the reference plan.
