Thank you very much for this video, can I use PSO if we have a constrain which is variables x1+x2+x3 must equal 100?

can you please explain about the active constraints of a PO with reference to the subject numarical methods. my exams are near and i didn't found any good video on yt about that.

Hello, many thanks for the video and the clear explanation! I have only one observation, at 26:01 when it shows the table "New pBest Value", the third row is showing 7.2179 but the correct value should be 2.2179. Maybe it is just a typo when designing the slides, not a big problem as the explanation is very good. Thanks again, your video helps a lot the easy understanding of PSO!

I do not know why the comments are always compliment. The explanation and mathematical notation can clearly be improved. For example, gBest is the best location of the particles in the swarm, but why in the formula the gBest has a subscript i? This is clearly inconsistent with the definition and will confuse a lot of people if they are really paying attention to the video. But everybody just oh, great video~

Hello @Yingkai As you asked Why gBest has a subscript i? i represents Particle position and t represent iteration number. so for each iteration we will select best particle mathematically ( i is used to represent candidate position number and t for iteration number).

If xi in t+1 = (x1 in t) + (vi in t), in minute 19:22 you say that we need to calculate (velocity i in t + 1), to calculate position (xi in t+1), but in the formula, it uses (vi in t), not (vi in t+1), its possible to use the previous iteration velocity, or is velocity in vi in t+1?

More precisely v1 in iteration 1 is 1.0667 and v1 in iteration 0 is 0.8, when you calculates x1 in iteration 1, in minute 22:46 the presentation said that the formula uses v1 in iteration 0, but you used 1.0667, my question is, its an error in the formula and x1 in iteration 1 = (x1 in iteration 0) + (v1 in iteration 1), or its an error in calculation and we need to use 0.8?

Relax 😇 1. We want to update Position of Particles / Birds. Right! 2. In order to update Position first we need to compute velocity. WHY? Because, we will add some Velocity in Position. [so that it can move] Done! 3. New Position = In Old Position + Add Velocity [done]. Here, New Position is denoted by: xi ^ t + 1; i = 1,2,3,4,....number of total particles. t = 1,2,3,4,5,...MaxT // Counter x = position v = velocity
