title: Iterative Deepening A* Star Explanation
body: <p>Can somebody explain about <strong>Iterative Deepening A*</strong>? I still don't understand how it works.
  <strong>Iterative deepening</strong> search w/ <strong>Depth First Search</strong>, and If still not found the solution; increase the <strong>Depth</strong>++ until found solution.</p>
  
  <p>If Iterative deepening using <strong>Depth</strong>, then Iterative Deepening A* use what to limit their search?</p>
  
  <p>Here are a picture if you need to explain how it IDA* Works, i just don't understand how it works.</p>
  
  <p><strong>(1,2,4,9)</strong> and etc, is the step</p>
  
  <p>0+2=2 is <strong>f(n)=g(n)+h(n)</strong></p>
