Introduction

Nodes

Variables

(Primitive) Boxes

Primitive function building-blocks:

• L, LI_in, A, C, D, I, etc...

Subgraphs (Containers)

• Well-defined order to boxes in the container
• has list of nodes: variables, functions, containers (subgraphs)
• has information in relation to rest of the graph:
  • parent (enclosing), scope

subgraph/container types:

• Function
  • DOES NOT YET INCLUDE: call vs. definition
• Conditional
  • condition
  • if-block, else-block
• Loop
  • loop condition
  • EXIT, BREAK, CONTINUE variables

Hyperedges

• list of uids of input variables
• uid of node
• list of uids of output variables

Lambdas / Expression Trees

• Primitive Operators
  • +, -, ...

Types

have Domain

Atomic

• int, float bool, etc…

Composite

• Sequence: Array, List, Tuple
• Dictionary: hash?
• struct
• user-defined
