有什么算法可以达到global optimum?
或者接近global optimum?
哪怕算法很复杂,centralized,都可以
只要能达到globaloptimum就行,
向各位求助了,有这样的算法吗?
谢谢! |

j*****n 发帖数: 1545 | 21 有一个functon f(x,y), 要找optimum. 直接优化x和y难度很大, 但是可以分别优化:
固定y, 优化x; 固定x, 优化y. 而且这个分别优化能够保证是 global optimum.
我的问题是我的这个迭代的算法能保证最后的结果是最优吗?
step 1: fix y_0, update x_0 to the optimal solution x_1
step 2: fix x_1, update y_1 to the optimal solution y_2
step 3: go to step 1 and iterate until convergence.
我觉得好像和conjugate gradient系列的算法很像, 但我一下想不出来我这个算法是对
还是错. 求指点. 如果有定理之类的可以参考最好!! |

家里用的网是optimum,接了一个belkin的wireless router,

其他的device就没法接入无线网了.
已经reset过router,里面默认的接入数量是100. 之前用得好好得.

k*******d 发帖数: 1340 | 24 My major is not CS and I have not touched this algo for several years. The
basic idea is that it is a greedy algorithm. Every step you try to find a
local optimum and there is a proof saying that doing this leads to global
optimum. Every step you include a unvisited node that is closest to the
visited node set.
It is not as difficult as you thought. Read the pseudocode and the
examples on wiki slowly in more detail. |

w****r 发帖数: 1046 | 28 You may take derivative with respect to xi to find your optimum f and g. But
the values of xi for the two optimization functions may differ.
Well, the optimum solution for maximizing the function of f(x)-g(x) probably
does not optimize f and g, simutaneously. Sometimes, it does.
Your problem is very similar to firm theory in microeconomics. |

for any quadratic plolynomial function, can I say there is a unique local
optimum if we define the local neighborhood as a unit ball ||x-y||<=1?
or simply consider the function defines on Z^n integer vectors.
Assume this function has a global optimum not at infinite.
Thanks a lot.

"real" optimum, as pointed out by another worm earlier, GA, Monte Carlo, NN
or any other fancy optimization techniques should be OK.
(1) If real optimum is of primary importance, it can be formulated as an integer
programming problem, or more strictly speaking, a binary optimization
problem. You might want to do the following
define decision variable d(i,j) such that
d(i,j)=0 if N(i)!=j
=1 if N(i)=j

z*******9 发帖数: 167 | 39 前天花了很多时间写了长篇大论,发在某版,呼吁大家用平和的心情聆听敌人的声音。
可惜斑竹没到10秒就删掉了,我估计他/她没有看完我的主旨就下手删除了。帖子已经
不在了,只好简单再写一遍。
911 发生后,很多美国民众在布什政府的宣传下,已经把聆听回教世界的声音的门关上
了。虽然有些人主张检讨美国对回教的政策,但毕竟不是主流。人类发展史上有数不清
的仇恨,即便到了文明的二十一世纪。然而仇恨已经让人厌倦了,我们已经不再需要仇
恨了。连一直以世界警察自居的美国,也开始向它原来的敌人发出善意,开始修补跟他
们的关系,那么一向注重以和为贵的中华民族就不能用更包容的心情去聆听敌人的声音
吗?
没有永远的敌人和朋友,只有永远的利益。中国内部的很多民族矛盾,我想也是某种意
义上的利益之争。既然矛盾存在,那么我们更应该回归理性,倾听对方的声音,寻求妥
协,达到总体利益的最大化。很明显,流血冲突不是一个最优解,it is way far away
from the optimum. 尽管我们只是看客,不是参与者,但我们的思想在流传,我们所
形成的网络意识会在很长一段时间里流传。从这个意义上看,我们是参与者。 |
