 | 
|  |     17 |   In the following theories a formalization of the Owicki-Gries and
 | 
|  |     18 |   the rely-guarantee methods is presented. These methods are widely
 | 
|  |     19 |   used for correctness proofs of parallel imperative programs with
 | 
|  |     20 |   shared variables.  We define syntax, semantics and proof rules in
 | 
|  |     21 |   Isabelle/HOL.  The proof rules also provide for programs
 | 
|  |     22 |   parameterized in the number of parallel components. Their
 | 
|  |     23 |   correctness w.r.t.\ the semantics is proven.  Completeness proofs
 | 
|  |     24 |   for both methods are extended to the new case of parameterized
 | 
|  |     25 |   programs. (These proofs have not been formalized in Isabelle. They
 | 
|  |     26 |   can be found in~\cite{Prensa-PhD}.)  Using this formalizations we
 | 
|  |     27 |   verify several non-trivial examples for parameterized and
 | 
|  |     28 |   non-parameterized programs.  For the automatic generation of
 | 
|  |     29 |   verification conditions with the Owicki-Gries method we define a
 | 
|  |     30 |   tactic based on the proof rules.  The most involved examples are the
 | 
|  |     31 |   verification of two garbage-collection algorithms, the second one
 | 
|  |     32 |   parameterized in the number of mutators.
