The Tree

inductive Aesop.NodeState : Type

At each point during the search, every node of the tree (goal, rapp or mvar cluster) is in one of these states:

Every node starts in the unknown state and may later become either proven or unprovable. After this, the state does not change any more.

inductive Aesop.GoalOrigin : Type

A goal G can be added to the tree for three reasons:

1. G was produced by its parent rule as a subgoal. This is the most common reason.
2. G was copied because it contains some metavariables which were assigned by its parent rule. In this case, we record goal of which G is a copy. We also record the representative of the equivalence class of goals which are copies of each other. E.g. if goal 1 is copied to goal 2 and goal 2 is copied to goal 3, they are all part of the equivalence class with representative 1.
