详情----------Details----------
One of the most versatile features of RedeR is the ability to deal with nested network objects using dynamic simulation, which makes it possible to represent, for example, subnetworks and time-series onto the same graph in a user-friendly routine. The simulation uses force-directed algorithms as described elsewhere (Brandes 2001; Fruchterman and Reingold 1991). Here we adapted the method to deal with nested networks. In force-directed graphs, each edge can be regarded as a spring - with a given target length - and can either exert a repulsive or attractive force on the connected nodes, while nodes are analogous to mutually repulsive charged particles that move according to the applied forces. In RedeR, the simulation is additionally constrained by the hierarchical structure. For example, a nested node is constrained to its parent-node by opposing forces applied by the nest, which is regarded as a special node whose nested objects can reach a local equilibrium independently from other network levels. The simulation is adjusted by global options and evolves iteratively (and interactively) until the system reaches the equilibrium state. The parameters controlling the dynamics are arbitrarily set to layout sparse networks with a few nodes (e.g. 10-100 nodes). For large and dense networks better results can be achieved interactively by tuning one or more parameters.
瑞德最多才多艺的特点之一是能够处理嵌套的网络使用动态模拟的对象，这使得它能够代表，例如，子网和时间序列上相同的图形中的一个用户友好的例行。模拟使用力导向其他地方所描述的算法（2001年布兰德斯; 1991年Fruchterman和莱因戈尔德）。在这里，我们调整的方法来处理嵌套的网络。在部队向图，每个边可以被视为一个春天 - 一个给定的目标长度 - 可以对所连接的节点上的排斥或吸引力，而节点是相互排斥的带电粒子移动根据应用类似力量。在瑞德，模拟加限制的层次结构。例如，一个嵌套的节点被限制在它的父节点反对巢，这是作为一个特殊的节点，嵌套对象，可以从其他网络水平达到当地平衡独立作用力。模拟全局选项调整和迭代演进（交互），直到系统达到平衡状态。动态控制参数任意设置稀疏的网络布局，有几个节点（如10-100节点）。对于大型和密集的网络，可以达到更好的效果，通过调整一个或多个参数的交互。
