title: fill this array with another arrays elements with genetic algorithm in pyevolve
body: <p>for example:</p>
  
  <pre><code>a=1500
  b=[500,400,200]
  </code></pre>
  
  <p>One answer is: </p>
  
  <pre><code>ans=[1,2,1]
  </code></pre>
  
  <p>because <code>1*500+2*400+1*200=1500</code> I want to write a program with genetic algorithm with best evaluation function to solve this problem with this array with pyevolve python evolutionary tool.</p>
