+"""Z3 is a high performance theorem prover developed at Microsoft Research. Z3 is used in many applications such as: software/hardware verification and testing, constraint solving, analysis of hybrid systems, security, biology (in silico analysis), and geometrical problems.
+
+Several online tutorials for Z3Py are available at:
+http://rise4fun.com/Z3Py/tutorial/guide
+
+Please send feedback, comments and/or corrections on the Issue tracker for https://github.com/Z3prover/z3.git. Your comments are very valuable.
+
+Small example:
+
+>>> x = Int('x')
+>>> y = Int('y')
+>>> s = Solver()
+>>> s.add(x > 0)
+>>> s.add(x < 2)
+>>> s.add(y == x + 1)
+>>> s.check()
+sat
+>>> m = s.model()
+>>> m[x]
+1
+>>> m[y]
+2
+
+Z3 exceptions:
+
+>>> try:
+...   x = BitVec('x', 32)
+...   y = Bool('y')
+...   # the expression x + y is type incorrect
+...   n = x + y

+    Thin C++ layer on top of the Z3 C API.
+    Main features:
+      - Smart pointers for all Z3 objects.
+      - Object-Oriented interface.
+      - Operator overloading.
+      - Exceptions for signining Z3 errors
+
+    The C API can be used simultaneously with the C++ layer.
+    However, if you use the C API directly, you will have to check the error conditions manually.
+    Of course, you can invoke the method check_error() of the context object.

+          T3: (R c d)
+          [trans* T1 T2 T3]: (R a d)
+          }
+          R must be a symmetric and transitive relation.
+
+          Assuming that this proof object is a proof for (R s t), then
+          a proof checker must check if it is possible to prove (R s t)
+          using the antecedents, symmetry and transitivity.  That is,
+          if there is a path from s to t, if we view every
+          antecedent (R a b) as an edge between a and b.

+
+          (= (f a (g c d))
+             (g (f a c) (f a d)))
+
+          If f and g are associative, this proof also justifies the following equality:

+             (g (f a c) (f a d) (f b c) (f b d)))
+

+          Remark: if f is bool, then = is iff.
+
+
+          Examples:
+          \nicebox{
+          (= (+ x 0) x)
+          (= (+ x 1 2) (+ 3 x))

+          This proof object has one antecedent: a hypothetical proof for false.
+          It converts the proof in a proof for (or (not l_1) ... (not l_n)),
+          when T1 contains the open hypotheses: l_1, ..., l_n.
+          The hypotheses are closed after an application of a lemma.

+          This proof object has no antecedents.
+          Note: all axioms are propositional tautologies.

+          You can recover the propositional tautologies by
+          unfolding the Boolean connectives in the axioms a small

+
+   - Z3_OP_PR_DEF_INTRO: Introduces a name for a formula/term.
+       Suppose e is an expression with free variables x, and def-intro
+       introduces the name n(x). The possible cases are:
+
+       When e is of Boolean type:
+       [def-intro]: (and (or n (not e)) (or (not n) e))
+
+       or:
+       [def-intro]: (or (not n) e)

+       [def-intro]: (and (or (not cond) (= n th)) (or cond (= n el)))
+
+       Otherwise:

+   - Z3_OP_PR_IFF_OEQ:
+       T1: (iff p q)
+       [iff~ T1]: (~ p q)
+
+   - Z3_OP_PR_NNF_POS: Proof for a (positive) NNF step. Example:
+       \nicebox{
+          T1: (not s_1) ~ r_1
+          T2: (not s_2) ~ r_2
+          T3: s_1 ~ r_1'

+          }
+       The negation normal form steps NNF_POS and NNF_NEG are used in the following cases:
+       (a) When creating the NNF of a positive force quantifier.
+        The quantifier is retained (unless the bound variables are eliminated).
+        Example
+        \nicebox{
+           T1: q ~ q_new
+           [nnf-pos T1]: (~ (forall (x T) q) (forall (x T) q_new))
+        }
+       (b) When recursively creating NNF over Boolean formulas, where the top-level
+       connective is changed during NNF conversion. The relevant Boolean connectives
+       for NNF_POS are 'implies', 'iff', 'xor', 'ite'.
+       NNF_NEG furthermore handles the case where negation is pushed
+       over Boolean connectives 'and' and 'or'.
+
+
+   - Z3_OP_PR_NNF_NEG: Proof for a (negative) NNF step. Examples:

+          }
+
+    - Z3_OP_PR_TH_LEMMA: Generic proof for theory lemmas.
+
+         The theory lemma function comes with one or more parameters.
+         The first parameter indicates the name of the theory.
+         For the theory of arithmetic, additional parameters provide hints for
+         checking the theory lemma.
+         The hints for arithmetic are:
+
+         - farkas - followed by rational coefficients. Multiply the coefficients to the
+           inequalities in the lemma, add the (negated) inequalities and obtain a contradiction.
+
+         - triangle-eq - Indicates a lemma related to the equivalence:
+         \nicebox{
+            (iff (= t1 t2) (and (<= t1 t2) (<= t2 t1)))
+         }

+
+
+    - Z3_OP_PR_HYPER_RESOLVE: Hyper-resolution rule.
+
+        The premises of the rules is a sequence of clauses.
+        The first clause argument is the main clause of the rule.
+        with a literal from the first (main) clause.
+
+        Premises of the rules are of the form
+        \nicebox{
+                (or l0 l1 l2 .. ln)
+        }
+        or
+        \nicebox{
+             (=> (and l1 l2 .. ln) l0)
+        }
+        or in the most general (ground) form:
+        \nicebox{
+             (=> (and ln+1 ln+2 .. ln+m) (or l0 l1 .. ln))
+        }
+        In other words we use the following (Prolog style) convention for Horn
+        implications:
+        The head of a Horn implication is position 0,
+        the first conjunct in the body of an implication is position 1
+        the second conjunct in the body of an implication is position 2
+
+        For general implications where the head is a disjunction, the
+        first n positions correspond to the n disjuncts in the head.
+        The next m positions correspond to the m conjuncts in the body.
+
+        The premises can be universally quantified so that the most
+        general non-ground form is:
+
+        \nicebox{
+             (forall (vars) (=> (and ln+1 ln+2 .. ln+m) (or l0 l1 .. ln)))
+        }
+
+        The hyper-resolution rule takes a sequence of parameters.
+        The parameters are substitutions of bound variables separated by pairs
+        of literal positions from the main clause and side clause.
+
+
+      - Z3_OP_RA_STORE: Insert a record into a relation.

+           target = filter_by_negation(pos, neg, columns)
+
+        where columns are pairs c1, d1, .., cN, dN of columns from pos and neg, such that
+        target are elements in x in pos, such that there is no y in neg that agrees with
+        x on the columns c1, d1, .., cN, dN.
+

+        and the remaining \c n arguments correspond to a record.
+
+      - Z3_OP_RA_CLONE: Create a fresh copy (clone) of a relation.
+        The function is logically the identity, but
+        in the context of a register machine allows
+        for #Z3_OP_RA_UNION to perform destructive updates to the first argument.

+      - Z3_OP_FD_LT: A less than predicate over the finite domain Z3_FINITE_DOMAIN_SORT.
+

+
+      - Z3_OP_LABEL_LIT: A label literal (used by the Boogie Verification condition generator).
+                     A label literal has a set of string parameters. It takes no arguments.

+       incremental solver (solver2). This combined solver changes its behaviour based
+       on how it is used and how its parameters are set.
+
+       If the solver is used in a non incremental way (i.e. no calls to
+       #Z3_solver_push() or #Z3_solver_pop(), and no calls to
+       #Z3_solver_assert() or #Z3_solver_assert_and_track() after checking
+       satisfiability without an intervening #Z3_solver_reset()) then solver1
+       will be used. This solver will apply Z3's "default" tactic.
+
+       The "default" tactic will attempt to probe the logic used by the
+       assertions and will apply a specialized tactic if one is supported.
+       Otherwise the general `(and-then simplify smt)` tactic will be used.
+
+       If the solver is used in an incremental way then the combined solver
+       will switch to using solver2 (which behaves similarly to the general
+       "smt" tactic).
+
+       Note however it is possible to set the `solver2_timeout`,
+       `solver2_unknown`, and `ignore_solver1` parameters of the combined
+       solver to change its behaviour.
+
+       The function #Z3_solver_get_model retrieves a model if the
+       assertions is satisfiable (i.e., the result is \c
+       Z3_L_TRUE) and model construction is enabled.
+       The function #Z3_solver_get_model can also be used even
+       if the result is \c Z3_L_UNDEF, but the returned model
+       is not guaranteed to satisfy quantified assertions.

+       \remark User must use #Z3_solver_inc_ref and #Z3_solver_dec_ref to manage solver objects.
