    Thank you so much ! It's just pretty amazing how we spent 2 sessions of 2 hours in an amphitheatre trying to learn this and turn the algorithm by following the literal code, and here I got it in literally 5 minutes. I'm so eternally grateful.

    Thank you so much for your fantastic work! I found learning these techniques by merely reading textbooks and listening to university lecturers pretty bland and counter-intuitive, but fortunately your visualized examples have given me a much clearer picture. in fact I started to understand the all the previously incomprehensible texts and pseudo-codes just after having seen your videos, and I would very much appreciate if you have any plans in the future to share further videos on NP-complete problems and approximation algorithms. Have a nice day!

    Wow my professor took about 20min to explain this and I didn't really get it. I thought it was hard, but after watching your video in 1/4th the time I am able to explain to others how to run the algorithm, and truly understand it. Turns out it isn't hard at all - just need someone good like you to explain it! Thanks a ton.

    Instead of only outputting the distance, it would be nice to add that, for each node one can keep track of the parent node where the current shortest distance is found, then traverse backwards from the destination to the source to obtain the shortest path.

    • @petosigut2271
      @petosigut2271 5 месяцев назад

      Very important, it is also missing in the pseudocode, the prev attribute is set to nil initially, but not changed in the update procedure
