An example of the results of running different ITM Probe models. Here we see the results of running the emitting (a,d,g), absorbing (b,e,h) and channel (c,f,i) model of ITM Probe with the same sources and sinks but different dissipation coefficients. The underlying undirected graph is derived from a square lattice by removing random nodes and edges. Sources are shown as hexagons, sinks as octagons, and transient nodes as squares. The top row (a,b,c) shows the runs with damping factor μ = 0.95 (dissipation 0.05), the middle (d,e,f) with μ = 0.75 and the bottom with μ = 0.25. For the emitting and channel model, each basic cyan, magenta or yellow color is associated with a source. The coloring of each node arises by mixing the basic color in proportion to the strength of information flow from their respective sources. For the absorbing model, the nodes are shaded according to the total probability of absorption at any sink on a logarithmic scale.
