Comparison between the EPR model and the recency-based (RM) model. (a) The analysis of the return ranks generated by the EPR model shows that it reproduces a pattern similar to the one observed from the empirical analysis, especially of D1. (b) On the other hand, on the presence of the recency mechanism, we can observe the same high probability of return to recently-visited locations (i.e., low \(K_{s}\)) as observed on the empirical data. (c) When we look at the distribution of the frequency ranks, the preferencial return mechanisms (labelled \(EPR\)) successfully exhibited a power-law distribution, in agreement with the empirical observations. Since the R1 data maintains the visitation frequencies, the \(K_{f}\) distribution of both variables are identical and hence their curves overlap. The activation of the recency mechanism does not affect the frequency rank distribution. (d) However, when we look at the \(K_{s}\) distribution, the EPR mechanism does not capture the power-law behavior observed on the empirical data.
