python - How to minimize matrix w with given equation and conditions? -

-

w 3*1 matrix , want minimize (w'seccovw), given w'*secmu = 6.5, w'*1 = 1. thank you!

import pandas pd import numpy np scipy.linalg import solve scipy import optimize  seccov = np.matrix('1 2 3, 4 5 6, 7 8 9') secmu = np.matrix('1.1 1.2 1.3').t  def minfunc (w, cov):     return w.t*cov*w

i'm having difficult time , hope guys can help. using helicon isapi rewrite version 3.1.0.104 on our iis server. edit http.conf file , have tried , still fail. this trying do: redirect url: https://www.domain.com/switch-by-version?version=2.8.5.2594 to: https://test.domain.com/load/load.aspx?tver=2.8.5.2594 the version number @ end source url change, , need target url have same version number @ end of url example above shows. i tried following not work: rewritecond %{query_string} ^version=(\d\d?)\.(\d\d?)\.(\d\d?)\.(.*)$ [nc] rewriterule ^/switch-by-version(.*)$ https://test.domain.com/load/load.aspx?tver=%1 [r=307,nc,l] any appreciated! thanks. if it's running in equivalent context of .htaccess , rule shouldn't start / . here's simpler version: rewritecond %{query_string} ^version=(\d+\.\d+\.\d+(?:\..+)?)$ [nc] rewriterule ^switch-by-version/?$ https://test.domain.com/load/load.aspx?tver=%1 [r=307,nc,l]

arrays - Algorithm to find ideal starting spot in a circle -

-
so problem have been debating such: your given array of integers representing circle. then, have pick spot in circle start. place start, compare value @ array number of steps took there , if steps less or equal number, include in final set. find place start have elements in set. ex, a=[0, 1, 2] if start @ index=0, then: a[0]=0 < =0 0 included a[1]=1 < =1 1 included a[2]=2 < =2 2 included final set: {0,1,2} if start @ index=1, then: a[1]=1 > 0 1 not included a[2]=2 > 1 2 not included here loop around a[0]=0 > 2 0 included final set: {0} if start @ index=2, then: a[2]=2 > 0 2 not included, here loop around a[0]=0 < = 1 0 included a[1]=1 < = 2 1 included final set: {0,1} so in trivial case, starting position index=0 best position results in final set elements. brute force method of finding obvious, trying find more efficient method. attempts far have been examine trying find max intersect of viable starting ranges calculated each element in arr...
