This appendix describes the code used in in the Applications section of "Myopia in dynamic spatial games" by Shane Auerbach and Rebekah Dix.
The script Construct_Oldenburg.m uses OLedges.txt and OLnodes.txt to create an undirected graph that represents the transportation network of Oldenburg, Germany using data from Brinkhoff (2002). The file OL.mat contains the output of Construct_Oldenburg.m.
The script Oldenburg_Spatial_Network_Simulation.m. can be used to simulate MBR agents on Oldenburg's transportation network. Furthermore, this script can be used more generally for simulations with myopic agents on any spatial network. This script uses the helper function FunCountTerritories.m. The file Oldenburg_Allocations.mat contains the particular sequence of spatial allocations discussed in the paper. To replicate the sequence of of spatial allocations, use the initial allocation of drivers in Oldenburg_Allocations.mat.
The script Create_Oldenburg_Figures.m creates the figures of Oldenburg's transportation network with allocations of drivers used in this paper. The script plots the initial, final, and approximately optimal allocations of drivers in Oldenburg_Allocations.mat and Oldenburg_Approx_Optimal.mat.
The file Greedy_Adjustment.m. uses a myopic (greedy) heuristic, as in Kuehn and Hamburger (1963), to compute an approximately optimal allocation of drivers on Oldenburg's transportation network. The file Oldenburg_Approx_Optimal.mat. contains the approximately optimal allocation of 60 drivers on Oldenburg's transportation network.
The computer game was developed in Matlab and uses the GUI Layout Toolbox (version 2.3.4), which is available through the Matlab File Exchange. This toolbox needs to be installed before running either the calculator or main console software. The game also uses export_fig, which is available in the Experiment folder.
To run the calculator, run calculator.m in Experiment/Calculator. To run the main console, run main.m in Experiment/Main Console.
