The value of the reinforcement parameter affects how rapidly the system is able to
adapt to changes in network composition. However, if the reinforcement parameter
is too large, the ranks will “chatter” and never converge to their correct value.
Consider the extreme case of α = 1. In this case, reinforcement will result ...
