这回不明白的地方多了。还请高手指点:
/ p5 l( {# }, j4 t
! ?7 b9 b/ x" d1.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。# x) s0 t9 T n0 N# E" t( _
6 g9 _" ]( t0 V2 I$ b2 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?& G6 o* ^8 E. p6 v, f, x2 l

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。0 U" [6 a$ R# E* g2 Y4 |# N
可是本质区别是什么哪?

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。5 |2 f+ r3 i% {& e8 l
