HOW HARD IS FOR AGENTS TO LEARN THE USER EQUILIBRIUM? CHARACTERIZING TRAFFIC NETWORKS BY MEANS OF ENTROPY Adv. Complex Syst. (IF 0.976) Pub Date : 2020-12-16 CAMIL S. Z. REDWAN; ANA L. C. BAZZAN
Traffic assignment is an important stage in the task of modeling a transportation system. Several methods for solving the traffic assignment problem (TAP) were proposed, mostly based on iterative procedures. However, little was done in the direction of analyzing the difficulty of such procedures. For instance, why is it that some networks require orders of magnitude more iterations than others? What

CONTROL CONTRIBUTION IDENTIFIES TOP DRIVER NODES IN COMPLEX NETWORKS Adv. Complex Syst. (IF 0.976) Pub Date : 2019-11-01 YAN ZHANG; ANTONIOS GARAS; FRANK SCHWEITZER
We propose a new measure to quantify the impact of a node $i$ in controlling a directed network. This measure, called `control contribution' $\mathcal{C}_{i}$, combines the probability for node $i$ to appear in a set of driver nodes and the probability for other nodes to be controlled by $i$. To calculate $\mathcal{C}_{i}$, we propose an optimization method based on random samples of minimum sets of

We assume a community whose members adopt one of two opinions A or B. Each member appears as an inflexible, or as a non-contrarian or contrarian floater. An inflexible sticks to its opinion, whereas a floater may change into a floater of the alternative opinion. The occurrence of this change is governed by the local majority rule: members meet in groups of a fixed size, and a floater then changes its
