16 FIG. 5: Coloured online. DPAD paths of state Fig. 2(c) with incomplete information. (a) TFL pattern with 50 L-RCs, randomly chosen, unknown. The pattern keeps the essential structure and exactly the same source loop of Fig. 3(b). (b) The same as (a) with di ff erent set of 50 L-RCs unknown. Now the source loop of Fig. 3(b) cannot be explored directly. However, this incomplete DPAD pattern is still very useful in exploring the driving structure of state Fig. 2(c). (c) Demonstration of the characteristics of periodic orbits of various nodes. Black solid, blue dash and red dash dot curves show u ( t ) signals of a given target center 8148, a node 5479 driving the target center 8148 via a L-RC, and a node 8550 without the L-RC driving (called normal node), respectively. In (c) the L-RC driving node (blue dash curve) has the characteristic of slightly hampered tail (see the small dot frame), clearly distinguishing from the normal node (red dash dot curve with perfectly smooth tail). This distinction has been verified to be common for all nodes t estified. (d) By applying the three conclusions in Sec. V and t he characteristic distinctions shown in Figs. 5(c) we can supplement all the missing long-range driving links of the source nodes in Figs. 5(a) and 5(b) (see dot arrows in (d) for patching Fig. 5(b)). Now the TFL pattern patched from Fig. 5(b) shows exactly the same self-organized oscillation structure as Fig. 3(b).
