蜜蜂在觅食过程中，往往要经过很多障碍物；同时，蜜蜂的飞行也有一定的方向性。
Honeybees, have a difficult task. They have to find food. Then they have to re- turn to the hive （蜂箱） to tell their partners where to find it. The bees have to fly back and forth between the hive and their food, over and over again. And they need to deal with whatever obstacles （障碍物） lie along their flight paths. ＂Honeybees face a lot of challenges in choosing efficient searching routes through dense （稠密的） environment. And we basically want to study how they choose effective routes the safest and least energy-expending routes.＂
