A general problem of chase algorithms is that they might perform redundant computations. WebJan 23, 2012 · The simple thing when you want to chase a target is to head directly toward it. This is what you did. However, the target will move in the meantime. So the algorithm is optimal only when the target does not move. The first element of complexity we can have is that the target has a fixed trajectory (that is unknown to the chaser). night stalker documentary free
