upper bound

基本解释

Doesn't need to be, so, what should I do about the upper bound here?
不必改下邊界值，因此,我該對上邊界值做個怎麽樣的改動呢？
Note that the demand for trains is unlimited, so a very large value is the upper bound on line 43.
注意對於火車的需求是無限的，因此在 43 行上我們使用了一個很大的值作爲上界。
Range Queries allow one to match documents whose field(s) values are between the lower and upper bound specified by the Range Query.
範圍查詢允許你指定某個字段最大值和最小值，查詢在二者之間的所有文档。

Oh, I could cheat and make, OK the upper bound a half, but that wouldn't be very honest.
噢，我可以像作弊一樣,把上界擴大兩倍，但這看起來沒什麽用。

So the basic idea was fine, but I failed to satisfy the initial condition that the answer had to be between the lower bound and the upper bound. Right?
因此基礎的思想是對的，但是程序沒能滿足,正確答案在給定的區間內這個條件,對不對？

All right? If you run it, you have a sense of the upper bound, about how much time it's going to take to do this computation, so you're not going to get surprised by something showing up.
第一，這樣做意味著沒有意外了對不對？,你去運行程序,你已經大致知道運行時間的上限了，因此發生任何事情,你都不會喫驚了。

My best guess would be that their calculation gives us an upper bound and the actual effect will be above zero but lower than their number.
