title: Project Euler problems which are not so math oriented
body: <p>I have started to solve PE problems a year ago, but within this year, I realised, that finding a problem which would be fun for me to think of is quite hard. I would like to solve problems more related with classic algorithms (graph theory, game theory, dynamic programming, divide and conquer...) and not so much of number theory and geometry (althought I like them too, but there was so much of them so far).</p>
  
  <p>Any tips? (first 50 problems already solved and second half of first hudnred almost too, so I would like to get some tips for problems from 100-200. 200+ are quite hard for me, I think)</p>
