Heuristics contain a stopping rule, often ending the search after only a few cures have been considered.
启发法包含一个终止原则,常常在只考虑几条线索后就终止搜索。
The only exception to this rule is where someone is in imminent danger of further injury which, in this case, could have been prevented by stopping what was relatively slow-moving traffic.
这个规则唯一的例外是如果不这样做的话这个人就有马上被继续伤害的危险。但在这个事件中,这可以让周围缓慢移动的车辆停下来来避免移动伤者。
Under some additional assumption, the optimal stopping rule is derived.
