structure Lean.Meta.Grind.Arith.Linear.Case : Type

• c : DiseqCnstr
• fvarId : FVarId

  Decision variable used to represent the case-split. For example, suppose we are splitting on p ≠ 0. Then, we create a decision variable h : p < 0

• saved : Struct

  Snapshot of the state for backtracking purposes. We do not use a trail stack.

instance Lean.Meta.Grind.Arith.Linear.instInhabitedCase : Inhabited Case

Equations

• Lean.Meta.Grind.Arith.Linear.instInhabitedCase = { default := { c := default, fvarId := default, saved := default } }

structure Lean.Meta.Grind.Arith.Linear.Search.State : Type

State of the model search procedure.

• cases : PArray Case

  Decision stack (aka case-split stack)

• decVars : FVarIdSet

  Set of decision variables in cases.
