The Weight setting alters the influence each constraint type provides to the overall, global solution.
If you are only using one layer, this can be left at the default, 100%.
If you are combining different constraints in several layers, you could reduce this weight to lessen the effects of the connections and blend in other layers.
This is a limit on the number of connections each particle can make.

Animation to demonstrate an increase in the Connection limit, from 1 to 5.
Particles will attract one another, but only if the distance between them is less than the Radius value.
The strength of attraction is given in this setting.
