Class ExpressionTreeVelocity<T>

Namespace
AiDotNet.LinearAlgebra
Assembly
AiDotNet.dll

Represents the velocity (rate and direction of change) for an expression tree during optimization.

public class ExpressionTreeVelocity<T>

Type Parameters

T

The numeric type used in the expression tree (e.g., double, float).

Inheritance
ExpressionTreeVelocity<T>
Inherited Members

Remarks

For Beginners: Think of this class as tracking how a mathematical formula should change during optimization. Just like velocity in physics describes how fast and in what direction an object is moving, this class describes how the formula is "moving" or changing during the optimization process. It keeps track of which numbers should change and how the structure of the formula might be modified.

Constructors

ExpressionTreeVelocity()

Initializes a new instance of the ExpressionTreeVelocity class with empty collections.

public ExpressionTreeVelocity()

Remarks

For Beginners: This creates a new, empty set of suggested changes for your formula. It's like starting with a blank slate before the optimization process fills in what changes should be made.

Properties

NodeValueChanges

A dictionary mapping node IDs to their value changes.

public Dictionary<int, T> NodeValueChanges { get; set; }

Property Value

Dictionary<int, T>

Remarks

For Beginners: This tracks how the constant numbers in your formula should change. For example, if your formula has "2x + 3" and the optimization suggests changing the 2 to 2.5 and the 3 to 3.2, this dictionary would store those suggested changes. The keys are the unique IDs of nodes in the expression tree, and the values are the amounts by which those nodes' values should change.

StructureChanges

A list of structural modifications to apply to the expression tree.

public List<NodeModification> StructureChanges { get; set; }

Property Value

List<NodeModification>

Remarks

For Beginners: This tracks changes to the structure of your formula, not just the numbers. For example, it might suggest replacing "x + y" with "x * y" in part of your formula. These are more dramatic changes than just adjusting coefficient values.
