C++ set lower_bound()用法及代码示例 - 纯净天空

WebA set with an upper (respectively, lower) bound is said to be bounded from above or majorized [1] (respectively bounded from below or minorized) by that bound. The terms bounded above ( bounded below) are also used in the mathematical literature for sets that have upper (respectively lower) bounds.

Web1 Aug 2024 · You can always find a set that is bounded above or below. The question is whether every such set will always have a least upper bound. Example: Let A 0 = { q q 2 < 2 } ⊂ Q. That IS bounded above by 2. But 2 is not the least upper bound. There is no least upper bound for that set.
