In computer science, particle swarm optimization (PSO) is a computational method that optimizes a problem by iteratively trying to improve a candidate solution with regard to a given measure of quality. It solves a problem by having a population of candidate solutions, here dubbed particles, and moving these particles around in the search-space according to simple mathematical formulae over the particle's position and velocity. Each particle's movement is influenced by its local best known position, but is also guided toward the best known positions in the search-space, which are updated as better positions are found by other particles. This is expected to move the swarm toward the best solutions.

sir can you provide related papers regarding the code ? It is difficult to understand the whole code.

please share the related papers for the objective function, References of PSO already available. Is this work compare with other methods? Is this code gives the correct features? Please share related publication...

Hello, thanks for the code, but it is not clear how or what you have used as your classifier to check the cost function of the PSO. Please can you clarify this?

please introduce the Related paper for this code ?

@LEE ZISHENG you can change fitness function.This algorithm select one best by given fitness function from group


Thank for your code. May i know is that the algorithms such as meandata and stddata can changes to other algorithms? Additionally, may i know is that this toolbox is applicable to automatic select the features without setting the number of feature to be selected?
Best regards,
Thank you..


hi. tanks for your code.
please introduce the Related paper for this code ?

hi im trying to do feature selection based on ant colony optimization ...can you suggest any related code...
