 This approach would be useful when a scenario needs multiple robots to collaboratively work together, such as when moving a box that is too big to be carried by a single robot. The researchers put their approach to the test in a computer model, running the LVWS method in competition against others in a case where there is a known, perfect solution for completion in the fastest amount of time. The new LVWS method was just 0.8% suboptimal compared to the 11.8% or worse suboptimal
