Decreasing spatial inequality in the city by adapting daily shopping destinations. a Decrease of wealth inequality among neighborhoods as a function of the fraction of transactions rewired, for various rewiring methods. Four combinations of choice heuristics are considered, “Uniform-Uniform”, “Uniform-Weighted”, “Weighted-Uniform” and “Weighted-Weighted”. b Decrease of wealth inequality (W k /W 0) while preserving the spatial mixing index (S k /S 0), the total distance traveled (D k /D 0) and the exploration rate (\(\bar {\rho }_{k}/\bar {\rho }_{0}\)), as a function of the number of rewiring operations. Values have been averaged over hundreds of replications. The bars represent the minimum and the maximum values obtained but in most cases are too close to the average to be seen (see Additional file 1: Figure S10-S11 for Madrid)
