This is the readme for "PSO" a Particle Swarm Optimizer object for PD/MAX.
This implimentation of a PSO minimizes towards a user-defined target. It is based on code from Jim Kennedy and Thomas Grill.

Follow the README.build.txt file for compilation instructions.
MAX: Put it in your externals folder.
PD: Put it in your extra folder.
The PSO object requires three arguments (see below). The object has one inlet and three outlets.
In order to calculate one iteration of the PSO send it a bang. The three outlets are:
Outlet 1: A index prepended list of the positions in each dimention of each particle.
Outlet 2: The Minimization value (should move towards 0)
Outlet 3: Outputs a bang when Minimization is reached. (This is a user defined threshold, not 0)
Arguments: [Population Size] [Number of Dimensions] [Neighborhood Size]
PSO Help Method:
'help' - This message.
PSO Setup Methods:
'target [list]' - Specify the optimization target with list of values for each dimension.
'rand_pop [min] [max]' - Randomize the population with values ranging from min to max.
'set_pop [list]' - Set population with list of values for each particle for each dimension.
'set_part [particle] [list]' - Set particle with values for each dimension.
'optim_thresh [int]' - Set the threshold at which minimization is considered reached. (0-10)
PSO Run-Time Methods:
'reset' - Reset the PSO.
bang - Calculate one interation of the PSO.
