PSO algortihm (parameter dimension)

Question

0.00/5 (No votes)

See more:

I am quite new to C# and PSO algorithm. Recently, I am trying to optimize multi-parameters (multi- variables) of an objective function. I gave the boundary limit to each parameter, and give the inital velocity for each parameter, but I found the trial point (parameter set) always jump out of the bounday. How to let the search point stay within the space? Or something wrong with initial vecocity?

Any people who knows the pso algorithm can give this help?

Thanks in advance.

Cheers,

Sharon

And did you understand what is it all about? I did not -- please see my comment below.

I guessed it is PSO ;-)
Yes, from the terms he uses, it's most likely Particle Swarm Optimization.
And I agree: using acronyms without spelled out full name is bad practice (especially if the term can be assumed to be only known to specialists).

Particle Swarm Optimization? Anything else? By using abbreviations, you assume too much; avoid it. Anyway, the question lacks detail.

Sorry, PSO is "Particle Swarm Optimization", I am thinking of "PSO" too much.

Google is your friend:[^]
E.g. see Particle swarm optimization for function optimization[^].

Certainly. Web is becoming more serious, reliable and informative, little by little.
