Fig. 3

The states and transition probabilities for two users and two CCs. The starting state is the node with the zero matrix (colored in orange). We use full edges when transition probabilities are equal for any value of \(\alpha\). When transitions depend on \(\alpha\) we use dotted edges. Labels represent the transition probabilities for (1) ExtremePA (\(\alpha = \infty\)), (2) PA with \(\alpha = 1\), (3) UR (\(\alpha = 0\)), (4) AntiPA with \(\alpha = -1\), and (5) ExtremeAntiPA (\(\alpha = - \infty\)) respectively. Dots replace zeros or probabilities when the starting state is not reachable from 0 under the respective recommendation process
