(5) CompletionProof (UPPER BOUND(ID))
The TRS is a completely defined constructor system, as every type has a constant constructor and the following rules were added:

   fstsplit(v0, v1) -> null_fstsplit [0]
   sndsplit(v0, v1) -> null_sndsplit [0]
   empty(v0) -> null_empty [0]
   length(v0) -> null_length [0]
   app(v0, v1) -> null_app [0]
   map_f(v0, v1) -> null_map_f [0]
   if2(v0, v1, v2) -> null_if2 [0]
   if3(v0, v1, v2) -> null_if3 [0]
   leq(v0, v1) -> null_leq [0]
   if1(v0, v1, v2) -> null_if1 [0]

And the following fresh constants:    null_fstsplit, null_sndsplit, null_empty, null_length, null_app, null_map_f, null_if2, null_if3, null_leq, null_if1, const

(21) RewriteLemmaProof (LOWER BOUND(ID))
Proved the following rewrite lemma:
FSTSPLIT(gen_0':s19_23(n27_23), gen_nil:cons:f20_23(n27_23)) -> gen_c:c1:c218_23(n27_23), rt in Omega(1 + n27_23)

Induction Base:
FSTSPLIT(gen_0':s19_23(0), gen_nil:cons:f20_23(0)) ->_R^Omega(1)
c

Induction Step:
FSTSPLIT(gen_0':s19_23(+(n27_23, 1)), gen_nil:cons:f20_23(+(n27_23, 1))) ->_R^Omega(1)
c2(FSTSPLIT(gen_0':s19_23(n27_23), gen_nil:cons:f20_23(n27_23))) ->_IH
c2(gen_c:c1:c218_23(c28_23))

We have rt in Omega(n^1) and sz in O(n). Thus, we have irc_R in Omega(n).

MAP_F < PROCESS
map_f < PROCESS
app < map_f
map_f < process
leq < PROCESS

(35) RewriteLemmaProof (LOWER BOUND(ID))
Proved the following rewrite lemma:
leq(gen_0':s19_23(n4577_23), gen_0':s19_23(n4577_23)) -> true, rt in Omega(0)

Induction Base:
leq(gen_0':s19_23(0), gen_0':s19_23(0)) ->_R^Omega(0)
true

Induction Step:
leq(gen_0':s19_23(+(n4577_23, 1)), gen_0':s19_23(+(n4577_23, 1))) ->_R^Omega(0)
leq(gen_0':s19_23(n4577_23), gen_0':s19_23(n4577_23)) ->_IH
true

We have rt in Omega(1) and sz in O(n). Thus, we have irc_R in Omega(n^0).

(37) RewriteLemmaProof (LOWER BOUND(ID))
Proved the following rewrite lemma:
length(gen_nil:cons:f20_23(n5104_23)) -> gen_0':s19_23(n5104_23), rt in Omega(0)

Induction Base:
length(gen_nil:cons:f20_23(0)) ->_R^Omega(0)
0'

Induction Step:
length(gen_nil:cons:f20_23(+(n5104_23, 1))) ->_R^Omega(0)
s(length(gen_nil:cons:f20_23(n5104_23))) ->_IH

We have rt in Omega(1) and sz in O(n). Thus, we have irc_R in Omega(n^0).

(45) RewriteLemmaProof (LOWER BOUND(ID))
Proved the following rewrite lemma:
sndsplit(gen_0':s19_23(n64485_23), gen_nil:cons:f20_23(n64485_23)) -> gen_nil:cons:f20_23(0), rt in Omega(0)

Induction Base:
sndsplit(gen_0':s19_23(0), gen_nil:cons:f20_23(0)) ->_R^Omega(0)
gen_nil:cons:f20_23(0)

Induction Step:
sndsplit(gen_0':s19_23(+(n64485_23, 1)), gen_nil:cons:f20_23(+(n64485_23, 1))) ->_R^Omega(0)
sndsplit(gen_0':s19_23(n64485_23), gen_nil:cons:f20_23(n64485_23)) ->_IH
gen_nil:cons:f20_23(0)

We have rt in Omega(1) and sz in O(n). Thus, we have irc_R in Omega(n^0).
