Both growth and update dynamics clearly represent big challenges for search engines.
While their model cannot be exactly mapped to ours for several reasons, such as the larger number of states or the kind of strategy update dynamics, the phenomenology is quite similar and the structures we have considered here are also identified as key factors to their findings.
In this table, the column LP refers to the (temporally) Local Properties: LP1 to LP17 (cf. [57]) and that specifies the update dynamics of the activation value of the 'to state' based on the activation levels of the 'from states'.
Remarkably, the choice of strategy update rule or update dynamics is much more important than the type of network imposed or, at least, the factorial effect of the average degree of the network reported by Nowak (Science 314, 5805, 1560 1563, 2006) and Ohtsuki et al. (Nature 441, 502 505, 2006).
On the other hand, hubs have been shown recently to play a role similar to the one discussed here under such a proportional update dynamics [37].
The updating dynamics of the intracellular GRN and of the intercellular movement of the mobile components were assumed to be synchronous and acted in a short-range.
The prediction uncertainty was computed after each trial with the updated dynamics along the current trajectory.
In the three strategy adoption rules we applied initially ('best-takes-over', 'pair-wise comparison dynamics' and 'proportional updating') all agents were myopic, and made their decisions based on the average payoffs gained in the previous round.
The proposed method is a hierarchical classification procedure, where the cluster splitting process is follows by the piecewise fitting process to compute the cluster guard and dynamics, and the cluster updating process to find new center points of the clusters.
In this research, failure formulation, controller structure and adaptive update rules for handling uncertainties from both the system dynamics and the failures are studied.
