This is such a hidden gem, I reached here after having to navigate through a lot of videos. But I'm fairly certain this is one of the best explanations on simulated annealing there is on TH-cam at the moment. Thank you for making these :)
i was having trouble understanding this thing from the book modern approach...and u made it so clear thanks a loot...it is amazing...:)..please put more of your videos ..really helpful
Is there an exact percentage about the solution quality against GAMS / Cplex solver. I determine lower and upper bound to generate neighbor for each x(i), decision variable. The limit is for lower bound between minus [1 3] and upper bound = abs(lower bound)*3, but it can approach just 70% to the GAMS / Cplex solution. Is it acceptable 70% or it is not good?
Great explanation of simulated annealing! Really clarifies the mechanism of the process. However, I have one question: What does the time and temperature in the algorithm mean? Is it just specific to the cool-down problem (what is the cool-down problem?) or is it a notation for something in simulated annealing?
I totally understand this but my question is what if there is no plateau ,ridges,shoulders,local maxima then this algorithm which includes simulated annealing will make the condition worse only because afer reaching the top of the peak (global maxima) it will check its neighbors obviously they will be having lower value.so according to this algorithm we will go from global maxima to a lower value.
how is the random succesor generated? is it just a completly random point on the landscape or does the successor stay closer and closer to the current state as the temperature cools down?
I'm pretty sure it's always completely random, but like he said, "bad" next moves are less likely to be assigned as the current. So yes, as time goes on, it will start to converge to the global maximum or minimum (hopefully) because it isn't choosing crappy moves. Hopefully you figured it out by now, given your comment was 3 months ago....Just thought I'd leave this here for other people too.

Great explanation, this should be the first video that appears when searching for simulated annealing.
Midterms in 8 hours and I've been mad procrastinating. You're my savior
stop bitching
I own you my exam. You are my saviour. Best explanation ever!!!
finally someone explained normally, thank you
your videos are great! but you gotta put your phone i silent mode :P haha

What a sweet sweet tutorial
This is great explanation. Is your source code available to play around with.

Great video! Straight out of the book and good explanations! :-) Great addition to the "Modern Approach"

Why isn't the video on genetic algorithms and local beam search in this play list?
do u have a calculation example for this algorithm if only one iteration?
do you have sample code for simulated annealing?
Very good explanation
Does anyone know how can I apply SA if my function f has constrains?
Very nice explanation.
Awesome animation, thank you!
Great lecture! :)
Thank you ... it was nice lesson
Well explained :)
Awesome ! thanks
