Arguments

object

A '>Leaf object.

val

The assigned value.

Methods (by generic)

• variables: List of '>Variable objects in the leaf node.

• parameters: List of '>Parameter objects in the leaf node.

• constants: List of '>Constant objects in the leaf node.

• is_convex: A logical value indicating whether the leaf node is convex.

• is_concave: A logical value indicating whether the leaf node is concave.

• is_quadratic: A logical value indicating whether the leaf node is quadratic.

• is_pwl: A logical value indicating whether the leaf node is piecewise linear.

• domain: A list of constraints describing the closure of the region where the leaf node is finite. Default is the full domain.

• validate_val: Check that val satisfies symbolic attributes of leaf.
