An algorithm may be stated in any dialect (or set of symbols, definitions and Various dialects (flow charts, Gantt charts, influence diagrams, and decision trees )

5th Edition, Prentice Hall, New Jersey, USA. Influence diagrams narrow the focus to critical decisions, inputs, and objectives. Decision trees in machine learning and data mining A decision tree can also be used to help build automated predictive models, which have applications in machine learning, data mining, and statistics. An Influence Diagram is a intuitive, graphical representation of a decision-problem. It is typically made up of 3 types of nodes (decisions, uncertainties, and values) and influencing arcs. Influence Diagrams are useful visual and communicative tools for displaying the main factors of a decision problem and the relationships between them. Visually, the diagrams are similar, and are generally distinguished by drawing blobs around the nodes of influence diagrams, but not around those of multiple cause diagrams. In some cases a systems practitioner will draw an influence diagram before going on to work on a multiple cause diagram, and this is mentioned in the T552 text.

Influence diagrams are hierarchical and can be defined either in terms of their structure or in greater detail in terms of the functional and numerical relation between diagram elements. An ID that is consistently defined at all levels—structure, function, and number—is a well-defined mathematical representation and is referred to as a well Most influence diagrams are used for static representations of a situation, but they can be the basis for a dynamic model and diagrams can be expanded to include a time factor. The key first step in construction of an influence diagram is specification of alternatives—which should be driven by firm goals and objectives—and key risks.

An influence diagram is an intuitive visual display of a decision problem. It depicts the key elements, including decisions, uncertainties, and objectives as nodes of various shapes and colors. It shows influences among them as arrows. Influence diagrams are directed acyclic graphs with three types of nodes—decision nodes, chance nodes, and a value node. Chance nodes, shown as circles, represent random variables (or uncertain quantities). Finally, the value node, shown as a diamond, represents the objective (or utility) to be maximized.

While the pure mathematical formalism of Bayesian networks does not require arcs to be causal, in influence diagrams all arc originating in decision nodes are causal and express the fact that making a decision impacts the nodes at the other end of the arcs. SmartDraw helps you quickly and easily create presentation-quality influence diagrams using built-in templates and intuitive drag-and-drop controls. You can also create decision trees and other business diagrams just as easily.
