	Particle initialization.
	Get particle of current request.
	Select the path with minimal training evaluation based on this request and current weights of index.
	Get routing path generalization evaluations index.
	Update according to current evaluation results.
	Update according to current evaluation results.
	Update particle velocity according to (5).
	Update particle position according to (6).
