Constraint Satisfaction: introduction 

Oh man, I love you. I wish I watched this short video instead of wasting more than an hour hearing my professor explaining it terribly.

That is really a very helpful lecture. I appreciate your efforts. You made us understand us complex concepts in AI in a very short time. Keep it up Dr.

John Levine has teached me more than entire courses I've taken honestly. The guy is a genius at teaching complex topics in very easy to understand videos.

This is the best explanation on introduction to CSPs

That was such an awesome explanation of not just CSP but also backtracking. I've always had a hard time showing back tracking in sequence. Thanks for sharing.

John, you are amazing ! I studied AI topics from your videos and got 96 and 100 from my exams. Thanks !

Concise,intuitive , and full bodied explaination

I love how you keep it simple, teaching only what we need to know because it helps me from getting overwhelmed. One video on the subject from you and I'm able to break down and solve more complex problems.

so much better than my professor thanks your videos might help me pass my A. I. class hopefully

Thank you very much for making this video! I've been struggling to understand backtracking based on textbook descriptions. Seeing it happen in real time was incredibly helpful.

Thank you. 👏👏 You made this easy for a topic I'm learning for the first time

Hello sir, just wanted to say that your videos are very concise and helpful. Thank you so much!

The better summary about Constraint Satisfaction! Thanks for this classroom!

Really helped with my understanding of the topic, cheers!

Thank you professor, you are brilliant! Toda!

Clearly explained, thanks for helping students

This reminds me of the way Prolog works a lot. Thanks for the vid!

Thanks for one of the best explanations I heard!

I will say this professor is always the best

Perfect lecture on Constraint Satisfaction. Hope to add fordward checking to prune the domains.

I had had a problem with assignment of domain variable values. I thought before that all three possible values had to be added and checked at the same time, in different orders. Boy was I wrong. Thanks for the clarification. Melted my frustration away in 7.

Thank you so much for this amazing lecture. Your way of explaining the content is really good understandable. You've just earned a new subscriber.

You are an excellent teacher, thank you!

You just made it so easier for us to understand, thank you so much respected Sir.

thanks a lot for your amazing videos, I really enjoy your channel

Thank you so much for making it easier and simple sir 😊

thank you. clear and concise. love it.

Thanks for the clear explanation, Im bulding a project in python and I really need to do it with that type of Algorithm now seems I can do it that way!

Very clear, thanks!!

Thankyou so much!!!!!!! I was stuck on this for 3 days..

Excellent explanation

Precise and clear 👏

Helpful, thanks.

really helpful. thank you sir.

superb job uncle

Thank you so much ❤️

Good introduction

print "Thank you for your concise explanation!"

How about options like A=3, B=1, C=2? Should we consider it?

thx for video

thank you :)

excelent

thank you for this video the guy who gave negative represents the only accepted solution in case of constrain = "minimum intelligence" I guess

Sir If we are going to forward then A=3, B=1 and C=2 and A=3, B=2 and C=1 that is also right answer According to this condition. My question is now what is the best answer.

given a CSP problem can you give and example of how you formulate the variables

I love you

would B not equal to C and A not equal to C be considered unary constrinats?

3:27 You dont know the value of B yet but you know the domain of B: 1,2,3 and there is not a value of B

Failin with 2,1,1 and moving to 2,1,3 is not calling a backtrack but a fail, right ? We backtrack only when there is no more values in the domain and that we go up in the levels.

So... the backtrack alg is exponential 🙈

They should call it the padlock algorithm

Wait, it's all sudoku?

There are other solutions (so that this is NOT complete) (A, B, C) = (3, 1, 2), (3, 2, 1), (3, 1, 1), and (3, 2, 2)
