Linear arithmetic, the lemmas SUB1-LESSEQP and SUB1-LESSP, and the definition

Give the conjecture the name *1.
We will appeal to induction. Two inductions are suggested by terms in
the conjecture, both of which are flawed. We limit our consideration to the
two suggested by the largest number of nonprimitive recursive functions in the
conjecture. Since both of these are equally likely, we will choose
arbitrarily. We will induct according to the following scheme:
(AND (IMPLIES (ZEROP X) (p X Y))
(IMPLIES (AND (NOT (ZEROP X)) (p (SUB1 X) Y))
(p X Y))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP inform
us that the measure (COUNT X) decreases according to the well-founded relation
LESSP in each induction step of the scheme. The above induction scheme
produces the following two new conjectures:
Case 2. (IMPLIES (ZEROP X)

This simplifies, applying TIMES-ZERO2, and opening up the functions ZEROP,

Case 1. (IMPLIES (AND (NOT (ZEROP X))
(EQUAL (TIMES (SUB1 X) Y)
(TIMES Y (SUB1 X))))

This simplifies, unfolding the definitions of ZEROP and TIMES, to the new
goal:

(NUMBERP X)
(EQUAL (TIMES (SUB1 X) Y)
(TIMES Y (SUB1 X))))
(EQUAL (PLUS Y (TIMES Y (SUB1 X)))
(TIMES Y X))).
Applying the lemma SUB1-ELIM, replace X by (ADD1 Z) to eliminate (SUB1 X).
We employ the type restriction lemma noted when SUB1 was introduced to
restrict the new variable. This produces the new goal:
(IMPLIES (AND (NUMBERP Z)
(NOT (EQUAL (ADD1 Z) 0))
(EQUAL (TIMES Z Y) (TIMES Y Z)))
(EQUAL (PLUS Y (TIMES Y Z))
(TIMES Y (ADD1 Z)))),
which further simplifies, applying the lemma TIMES-ADD1, to:
T.
So we now return to:
(EQUAL 0 (TIMES Y 0)),
which is formula *1.1 above. We will try to prove it by induction. There is
only one suggested induction. We will induct according to the following
scheme:
(AND (IMPLIES (ZEROP Y) (p Y))
(IMPLIES (AND (NOT (ZEROP Y)) (p (SUB1 Y)))
(p Y))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP
establish that the measure (COUNT Y) decreases according to the well-founded
relation LESSP in each induction step of the scheme. The above induction
scheme produces two new conjectures:
Case 2. (IMPLIES (ZEROP Y)

used to show that the measure (COUNT Y) decreases according to the
well-founded relation LESSP in each induction step of the scheme. Note,
however, the inductive instance chosen for Z. The above induction scheme
produces two new conjectures:
Case 2. (IMPLIES (ZEROP Y)
(EQUAL (LESSP (TIMES Y X) (TIMES X Z))
(AND (NOT (ZEROP X)) (LESSP Y Z)))),
which simplifies, applying EQUAL-TIMES-0, EQUAL-BOOLS, TIMES-ZERO2, and
COMMUTATIVITY-OF-TIMES, and unfolding ZEROP, EQUAL, TIMES, LESSP, NOT, AND,
and OR, to:
T.
Case 1. (IMPLIES (AND (NOT (ZEROP Y))

(AND (NOT (ZEROP X))
(LESSP (SUB1 Y) (SUB1 Z)))))
(EQUAL (LESSP (TIMES Y X) (TIMES X Z))
(AND (NOT (ZEROP X)) (LESSP Y Z)))).
This simplifies, applying EQUAL-BOOLS and COMMUTATIVITY-OF-TIMES, and
unfolding the definitions of ZEROP, NOT, AND, OR, LESSP, TIMES, and EQUAL,
to four new formulas:
Case 1.4.
(IMPLIES (AND (NOT (EQUAL Y 0))

(NOT (LESSP (TIMES (SUB1 Y) X)
(TIMES X (SUB1 Z))))
(NOT (LESSP (SUB1 Y) (SUB1 Z))))
(NOT (LESSP (TIMES X Y) (TIMES X Z)))),
which further simplifies, applying COMMUTATIVITY-OF-TIMES, to the new
formula:

(NOT (LESSP (TIMES X (SUB1 Y))
(TIMES X (SUB1 Z))))
(NOT (LESSP (SUB1 Y) (SUB1 Z))))
(NOT (LESSP (TIMES X Y) (TIMES X Z)))).
Applying the lemma SUB1-ELIM, replace Y by (ADD1 V) to eliminate (SUB1 Y).
We employ the type restriction lemma noted when SUB1 was introduced to
restrict the new variable. We thus obtain:

(NOT (LESSP (TIMES X V)

Applying the lemma SUB1-ELIM, replace Z by (ADD1 W) to eliminate (SUB1 Z).

Appealing to the lemma DIFFERENCE-ELIM, we now replace X by (PLUS Y Z) to
eliminate (DIFFERENCE X Y). We employ the type restriction lemma noted when
DIFFERENCE was introduced to constrain the new variable. This generates
three new conjectures:
Case 2.3.
(IMPLIES (AND (LESSP X Y)
(LESSP (PLUS A X) (PLUS A Y)))
(EQUAL (DIFFERENCE (PLUS A X) (PLUS A Y))
(DIFFERENCE X Y))),
which we would normally push and work on later by induction. But if we
must use induction to prove the input conjecture, we prefer to induct on
the original formulation of the problem. Thus we will disregard all that
we have previously done, give the name *1 to the original input, and work
on it.
So now let us return to:
(EQUAL (DIFFERENCE (PLUS A X) (PLUS A Y))
(DIFFERENCE X Y)).
We named this *1. We will try to prove it by induction. The recursive terms
in the conjecture suggest four inductions. They merge into two likely
candidate inductions. However, only one is unflawed. We will induct
according to the following scheme:
(AND (IMPLIES (ZEROP A) (p A X Y))
(IMPLIES (AND (NOT (ZEROP A)) (p (SUB1 A) X Y))
(p A X Y))).
Linear arithmetic, the lemmas SUB1-LESSEQP and SUB1-LESSP, and the definition
of ZEROP can be used to prove that the measure (COUNT A) decreases according
to the well-founded relation LESSP in each induction step of the scheme. The
above induction scheme produces the following two new goals:
Case 2. (IMPLIES (ZEROP A)
(EQUAL (DIFFERENCE (PLUS A X) (PLUS A Y))
(DIFFERENCE X Y))).
This simplifies, using linear arithmetic, to the following two new goals:
Case 2.2.

(ZEROP A))
(EQUAL (DIFFERENCE (PLUS A X) (PLUS A Y))

But this again simplifies, applying PLUS-RIGHT-ID, and opening up the

But this again simplifies, expanding the definitions of ZEROP, EQUAL, and
PLUS, to six new formulas:

well-founded relation LESSP in each induction step of the scheme. Note,
however, the inductive instance chosen for Y. The above induction scheme

Linear arithmetic, the lemmas COUNT-NUMBERP and COUNT-NOT-LESSP, and the
definition of ZEROP establish that the measure (COUNT X) decreases according
to the well-founded relation LESSP in each induction step of the scheme. The
above induction scheme produces the following three new formulas:

Applying the lemma REMAINDER-QUOTIENT-ELIM, replace X by (PLUS Z (TIMES J V))
to eliminate (REMAINDER X J) and (QUOTIENT X J). We rely upon LESSP-REMAINDER,
the type restriction lemma noted when REMAINDER was introduced, and the type
restriction lemma noted when QUOTIENT was introduced to restrict the new
variables. We thus obtain the following four new conjectures:
Case 4. (IMPLIES (NOT (NUMBERP X))
(EQUAL (REMAINDER (PLUS X (TIMES I J)) J)
(REMAINDER X J))).
But this simplifies, opening up the definitions of PLUS, LESSP, and
REMAINDER, to the conjecture:
(IMPLIES (NOT (NUMBERP X))
(EQUAL (REMAINDER (TIMES I J) J) 0)),
which we would usually push and work on later by induction. But if we must
use induction to prove the input conjecture, we prefer to induct on the
original formulation of the problem. Thus we will disregard all that we
have previously done, give the name *1 to the original input, and work on it.
So now let us consider:
(EQUAL (REMAINDER (PLUS X (TIMES I J)) J)
(REMAINDER X J)),
which we named *1 above. We will appeal to induction. There are three
plausible inductions. However, only one is unflawed. We will induct
according to the following scheme:
(AND (IMPLIES (ZEROP I) (p X I J))
(IMPLIES (AND (NOT (ZEROP I)) (p X (SUB1 I) J))
(p X I J))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP inform
us that the measure (COUNT I) decreases according to the well-founded relation
LESSP in each induction step of the scheme. The above induction scheme leads
to the following two new goals:
Case 2. (IMPLIES (ZEROP I)

Applying the lemma REMAINDER-QUOTIENT-ELIM, replace X by
(PLUS V (TIMES J Z)) to eliminate (QUOTIENT X J) and (REMAINDER X J). We
employ LESSP-REMAINDER, the type restriction lemma noted when QUOTIENT was

introduced to restrict the new variables. This produces the following two
new goals:

(IMPLIES (AND (NOT (NUMBERP X))

formulas:

must use induction to prove the input conjecture, we prefer to induct on
the original formulation of the problem. Thus we will disregard all

and work on it.
So now let us return to:
(EQUAL (QUOTIENT (PLUS X (TIMES I J)) J)
(IF (ZEROP J)

We named this *1. We will try to prove it by induction. Four inductions are
suggested by terms in the conjecture. They merge into three likely candidate
inductions. However, only one is unflawed. We will induct according to the
following scheme:
(AND (IMPLIES (ZEROP I) (p X I J))
(IMPLIES (AND (NOT (ZEROP I)) (p X (SUB1 I) J))
(p X I J))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP can be
used to establish that the measure (COUNT I) decreases according to the
well-founded relation LESSP in each induction step of the scheme. The above
induction scheme generates the following two new conjectures:
Case 2. (IMPLIES (ZEROP I)

Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP inform
us that the measure (COUNT SIZE) decreases according to the well-founded

This conjecture simplifies, obviously, to the following two new conjectures:

Give the above formula the name *1.
Case 1. (IMPLIES (ALL-ONESP A)
(EQUAL (BV-TO-NAT (INCR T A)) 0)),
which we would usually push and work on later by induction. But if we must
use induction to prove the input conjecture, we prefer to induct on the
original formulation of the problem. Thus we will disregard all that we
have previously done, give the name *1 to the original input, and work on it.
So now let us consider:
(EQUAL (BV-TO-NAT (INCR T A))
(IF (ALL-ONESP A)
0
(ADD1 (BV-TO-NAT A)))),
which we named *1 above. We will appeal to induction. The recursive terms in
the conjecture suggest three inductions. However, they merge into one likely
candidate induction. We will induct according to the following scheme:

(IMPLIES (AND (BITVP A)

Linear arithmetic and the lemma VEC-LESSP inform us that the measure (COUNT A)
decreases according to the well-founded relation LESSP in each induction step
of the scheme. The above induction scheme leads to the following three new
conjectures:

which we would normally push and work on later by induction. But if we must
use induction to prove the input conjecture, we prefer to induct on the
original formulation of the problem. Thus we will disregard all that we
have previously done, give the name *1 to the original input, and work on it.
So now let us return to:
(EQUAL (BITN A (SIZE A))
(IF (ZEROP (SIZE A))
F
(NOT (LESSP (BV-TO-NAT A)
(EXP 2 (SUB1 (SIZE A))))))).
We named this *1. We will try to prove it by induction. There are four
plausible inductions. However, they merge into one likely candidate induction.
We will induct according to the following scheme:
(AND (IMPLIES (AND (BITVP A) (EQUAL A (BTM)))
(p A))
(IMPLIES (AND (BITVP A)
(NOT (EQUAL A (BTM)))
(p (VEC A)))
(p A))
(IMPLIES (NOT (BITVP A)) (p A))).
Linear arithmetic and the lemma VEC-LESSP can be used to establish that the
measure (COUNT A) decreases according to the well-founded relation LESSP in
each induction step of the scheme. The above induction scheme leads to the
following three new conjectures:
Case 3. (IMPLIES (AND (BITVP A) (EQUAL A (BTM)))
(EQUAL (BITN A (SIZE A))
(IF (ZEROP (SIZE A))
F

EQUAL, to:

BV-TO-NAT, EQUAL, PLUS, and EXP, to 12 new conjectures:

Call the conjecture *1.
We will try to prove it by induction. There are three plausible
inductions. However, they merge into one likely candidate induction. We will
induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p A N))
(IMPLIES (AND (NOT (ZEROP N))

Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP inform
us that the measure (COUNT N) decreases according to the well-founded relation
LESSP in each induction step of the scheme. Note, however, the inductive
instance chosen for A. The above induction scheme generates two new goals:

Call the above conjecture *1.
Case 1. (IMPLIES (EQUAL (BV-TO-NAT A) 0)

which we would normally push and work on later by induction. But if we must
use induction to prove the input conjecture, we prefer to induct on the
original formulation of the problem. Thus we will disregard all that we
have previously done, give the name *1 to the original input, and work on it.
So now let us return to:
(EQUAL (ALL-ONESP (COMPL A))

suggested by terms in the conjecture. However, they merge into one likely
candidate induction. We will induct according to the following scheme:

decreases according to the well-founded relation LESSP in each induction step
of the scheme. The above induction scheme generates three new conjectures:
