PSO To Do's #82

Open mcw92 opened 1 year ago

mcw92 commented 1 year ago

Think about how to do migration with PSO in Propulate. Check how multi-swarm PSO works in general. The general mechanism is different from the island model used with GAs.
Fix position synchronization between dict and array-type position field in Particle class.
Make personal and global best attributes of PSO propagators. Currently, they are determined from scratch in every update step.
Combine basic PSO and velocity clamping in one propagator. Enable / disable velocity clamping with bool flag.

To the second bullet point - as I already pointed out in the test run and will point out again in the final presentation as well as in my thesis, please note, that run time efficient synchronization between the explicit and the implicit position fields of the Particle class are only possible in the direction pointing away from the explicit position field and only, if it is ensured, that one cannot change single values of this field without the Particle noticing this. In this case, field synchronization might become impossible.
