2 E0 V4 t8 y) I6 l! t) C' o$ D5 K; q" q2 x4 h* v
这回不明白的地方多了。还请高手指点:, N! Y1 I# A. \. l' k
( T5 A0 w. x) }- C) P# V
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。
$ o* {: A, o% \% M& M A
! g- H* c: C" H2 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.
$ M9 E5 \2 |# M7 u7 E6 n" @
9 ^; E, _5 N: q3. 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 `9 q) U4 a( j& n, Y+ d- |/ B% e" M6 Y
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。
9 C& N. j6 K F5 l' E3 R3 F6 q可是本质区别是什么哪?
# g" v) M3 g1 w1 {+ } x
% Z6 B* T+ `5 v9 m5.一样大。. j" g# Y/ C7 K9 d/ L+ h
- h3 n. V6 c0 i* o' {7 u" I6.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。
