这回不明白的地方多了。还请高手指点:

1.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。. I3 T, w9 B$ \7 X6 `9 |2 `/ W0 m8 A

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. 8 |% O% _ _, I, _' N* s8 D' O* q
$ J2 D ?4 L, v. \6 r# i; `# }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?

1 ?0 I9 T( S. I! h( x* S) K4.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。
+ J& |; h' a+ p可是本质区别是什么哪?

5.一样大。; \& ?9 e' V1 Z" C2 q7 K

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。
