-The example consists of two sets of maps extracted from IDRISI tutorial: land use map (worcwest), source map (newplant) and destination map (powerline). The first one at 15 meter resolution composed of 960 columns x 960 rows and the second at 5 meter resolution composed of 2880 columns x 2880 rows (respectively, folders ''resource'' and ''resource5''). Dinamica EGO models are in folders ''ego_15m'' and ''ego_5m''; we made available models with 2, 3 passes and optimum solution. In general, only two to three passes are needed to approximate to an optimum solution. Respective models implemented on MacroModeler are located in ''Idrisi_15m'' and ''Idrisi_5m'' (you might need to specify the working directory before running the Idrisi model), and folder ''arcgis'' contains the ModelBuilder model((Go to Arctool; you will need to add the model as a toolbox and then click on it to open and run the ModelBuilder model)).

-Figures below show the pathways calculated with three passes and another with optimum solution using Dinamica EGO as well as the pathways output from MacroModeler and ModelBuilder. Table below show the performance figures for the three platforms. To run the tests, we used a laptop VAIO Intel i5 CPU with 8 GB of RAM, solid state disk, and Windows Seven 64 bits. Dinamica version was 1.8, IDRISI version was IDRISI 32, v.2 and Taiga. ArcGis version was 9.3.
