摘要： A system and method for drawing curved edges in graphs is disclosed. The system and method implement a heuristic algorithm to draw curved edges in graphs using Bezier curves. The algorithm assumes that every pair of nodes has a unique edge between them. It also assumes that the graph is “leveled,” which means the nodes can be grouped such that all the nodes in a group are laid out at the same y location in a vertical layout. Any generic graph can be converted to a leveled graph, so the techniques described in the algorithm are applicable to any graph.

摘要： Techniques for visualization of decision logic are provided. In one aspect, the techniques can be implemented by providing a control within a graphical user interface to a user. The control can display a plurality of graphical user interface elements corresponding to linked nodes within a hierarchical structure. An input identifying a selected graphical user interface element within the control can be generated by a user. A selected node within the hierarchical structure can be identified based on the selected graphical user interface element. In response to a request from a user, modifying an appearance of a subset of the linked nodes within the hierarchical structure based on a desired visualization criteria, the linked nodes within the hierarchical structure and the selected node.

摘要： A system and method for drawing directed acyclic graphs is disclosed. In particular, an algorithm, as implemented in a method and system, to aesthetically layout directed acyclic graphs is presented. The algorithm includes methods to reduce the number of edge crossings and increase the number of straight edges in such drawings. The algorithm keeps short and straight edges wherever possible and gives preference to vertical edges. It also provides an edge-crossing reduction heuristic to refine the layout obtained after standard median heuristic layout, and further provides a method to focus on important paths in the graph through layout.
摘要翻译： 公开了用于绘制有向无环图的系统和方法。 特别地，呈现了在方法和系统中实现的用于美观地布置有向无环图的算法。 该算法包括减少边缘交叉的数量并增加这些图中的直边数的方法。 该算法尽可能保持短和直的边缘，并优先于垂直边缘。 它还提供了一个边缘交叉减少启发式来改进在标准中间启发式布局之后获得的布局，并进一步提供了一种通过布局集中在图中重要路径的方法。

摘要： The invention comprises an article and method for transforming a complex or large decision tree having multiple variables; multiple values for each variable; and, multiple outcomes for each combination of variables and their associated values, into a compact, efficient graphical representation to provided enhanced ease of use and interaction by a human user. More particularly, the invention comprises a computationally efficient method for transforming an input decision tree into an optimal compact representation by computing a particular ordering of variables in the decision tree that first leads to a Directed Acyclic Graph, or “DAG,” with a minimum number of nodes. The method then converts the DAG into an exception-based DAG, or “EDAG,” with exactly one exception, having an optimal, minimum number of nodes with increased comprehensibility for a user.

摘要： A request to compare strategies is received. The first strategy can be graphically represented by a first set of linked nodes arranged in a first form of decision logic. The second strategy can be graphically represented by a second set of linked nodes arranged in a second form of decision logic. The first set of linked nodes can be converted to a first modified set of linked nodes arranged in a third form of decision logic. The second set of linked nodes can be converted to a second modified set of linked nodes arranged in the third form of decision logic. A color-coded visual representation of the first modified set of linked nodes and the second modified set of linked nodes can be provided to a user. Related apparatus, techniques, and articles are also described.
