title: Weight change for an MST algorithm
body: <p><a href="https://i.stack.imgur.com/joSJ7.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/joSJ7.png" alt="enter image description here"></a></p>
  
  <p>Given the graph above and edge weights, if we increase the weight of edge A-B by 10.5, it would be no longer in MST.</p>
  
  <p>If we increase by 7.5 or 4.5 or 1.5 - it would still be. Why? I am trying to solve these problems on my own.</p>
  
  <p>Thank you.</p>
