Program Transformation for Program Verification

open access: yesEPiC Series in Computing, 2018
We present a transformational approach to program verification and software model checking that uses three main ingredients:(i) Constraint Logic Programming (CLP),(ii) metaprogramming and program specialization, and(iii) proof by transformation.
