Nuprl Lemma : lg-search_wf

[T:Type]. ∀[G:LabeledGraph(T)]. ∀[P:T ⟶ 𝔹].  (lg-search(G;x.P[x]) ∈ ℕlg-size(G)?)


Proof




Definitions occuring in Statement :  lg-search: lg-search(G;x.P[x]) lg-size: lg-size(g) labeled-graph: LabeledGraph(T) int_seg: {i..j-} bool: 𝔹 uall: [x:A]. B[x] so_apply: x[s] unit: Unit member: t ∈ T function: x:A ⟶ B[x] union: left right natural_number: $n universe: Type
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T lg-search: lg-search(G;x.P[x]) all: x:A. B[x] implies:  Q nat: so_lambda: λ2x.t[x] int_seg: {i..j-} exposed-bfalse: exposed-bfalse bool: 𝔹 unit: Unit it: btrue: tt ifthenelse: if then else fi  uiff: uiff(P;Q) and: P ∧ Q uimplies: supposing a bfalse: ff exists: x:A. B[x] prop: or: P ∨ Q sq_type: SQType(T) guard: {T} bnot: ¬bb assert: b false: False lelt: i ≤ j < k nequal: a ≠ b ∈  ge: i ≥  decidable: Dec(P) satisfiable_int_formula: satisfiable_int_formula(fmla) not: ¬A top: Top so_apply: x[s] subtype_rel: A ⊆B
