我的任务是使用Ruby制作更高效的二进制搜索代码.我按照这个链接的逻辑:http: //www.cprogramming.com/discussionarticles/sorting_and_searching.html

我的代码如下:

def bsearch(a, k)

  lower = 0
  upper = a.length-1

  while a[upper].to_f> k.to_f and a[lower].to_f< k.to_f
    low_diff = k.to_f -a[lower].to_f
    range_diff = a[upper].to_f-a[lower].to_f
    count_diff = upper-lower
    range = low_diff/range_diff * count_diff  + lower

    if k==a[lower]
      return lower

    if k.to_f > a[range].to_f
      lower = range+1
    else if k.to_f <  a[range].to_f
      upper =range
    else    
      lower = range
    end

  end
end

我仔细检查,但我不知道为什么我一直遇到以下错误:

unexpected $end , expecting kEND

您好,我正在尝试实施一个简单的负载平衡实验:在可用的3个负载均衡器调度算法之间进行更改:请求计数,加权流量计数和待处理请求计数.

参考:http://httpd.apache.org/docs/2.2/mod/mod_proxy_balancer.html 我在apache服务器中配置了我的conf文件:

码:

<IfModule ssl_module>
SSLRandomSeed startup builtin
SSLRandomSeed connect builtin
</IfModule>
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
 LoadModule proxy_module modules/mod_proxy.so
  LoadModule proxy_http_module modules/mod_proxy_http.so

 JkLogLevel    info
   JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
  #JkMount  /examples/jsp/dates* balancer

#此代理标记用于待处理请求计数算法BalancerMember ip1 loadfactor = 1 BalancerMember ip2 loadfactor = 1

 ProxySet lbmethod=byrequests#Request Counting Algorithm
 BalancerMember http://192.168.0.2/ # Balancer member 1
 BalancerMember http://192.168.0.10/ # Balancer member 2
  ProxySet lbmethod=bybusyness
  </Proxy>

但是,我不断收到错误:在某个位置定义时,BalancerMember不能有平衡器名称

从这一行:BalancerMember"//192.168.0.2/"#Balancer成员1 …
