题目在: ?( C# K$ G! t( G) W! q( Y7 I

这回不明白的地方多了。还请高手指点:1 s* {4 G0 [* V
, _4 [. y- ~& \8 h1.不知道。 高低中音什么的一点都不知道。不过解题思路就是找可能的组合个数。0 _0 j+ w3 K- Z* d9 p7 f, [9 J

2 well, I can reason a bit from the names of these optimization types. The advantage of randomized optimization is for looking for global minimum without being trapped by a local minimum (which is often the case for deterministic optimization). so far (a few years ago before I left school, to be accurate) optimization is cursed by dimensionality, and random optimization has only limited success.

3. 没听说过傅里叶空间插值。如果有的话也不奇怪。那么像实空间插值类似,傅里叶空间插值能准确复原已知频率的结果。别的还有什么呢?5 p( u+ Y" q5 j8 w- U' y! W( @

4.不知道。我只知道复数比较奇妙。有个柯西定理,复函数如果一阶可导,则无穷阶可导。这在实函数是不可能的。
" h1 H+ _( z2 K" m4 t1 p! v9 l可是本质区别是什么哪?, B2 ~& N% a# Q8 Z7 u

6.蒙特卡洛的实质?我也不知道。它的误差是 O(1/sqrt(N)), N是sample个数。
