“…To compare the performance of our algorithm with other methods, as mentioned in the introduction, there are not many previous works studying the problem in 3D, and among them, only our previous work in [16] (a moth-inspired algorithm) Table III. has comparable environmental conditions and experimental setup. Compared to [16], our new method has a better over-all success rate, especially at higher wind speeds (e.g., in setup E, the 3D infotaxis shows 100% success rate, whereas in [16] it was 70%). It is relatively slower in finding the source, due to the concentration sampling time at every step, but this difference is not very significant.…”
