title: Compare different search algorithms
body: <p>In what ways are DFS and Best-first search similar? How are BFS and Best-first similar?</p>
  
  <p>To me, to better decribe how DFS and BestFS are similar, it might be    easier to point the difference,which is that in BestFS we chose as the next to  expand the one that seems closest to the goal using the heuristi function. In almost all other  ways both of the best and DFS are similar.</p>
  
  <p>However I find it hard to find the similarities between BFS and BestFS</p>
