Proving the Correctness of Program Transformations with Abstract Execution and REFINITY
Summary. Abstract Execution (AE) is a new program analysis technique for automatically proving second-order properties about programs. It is based on the symbolic execution of abstract programs with second-order symbolic stores.

Report about the 1st International HacKeYthon 2018
Table of Contents
Two weeks ago, at the 6th and 7th of December, 2018, the 1st International HacKeYthon took place in the rooms of the KIT in Karlsruhe, Germany. In five groups consisting of 3 to 4 participants each we worked on small projects contributing to the overall good of the KeY system. The projects were addressing properties such as usability and performance of the system which are frequently ignored or postponed since their direct value for research is limited.

KeY’s SED Successfully Applied in an Industrial Setting
The Symbolic Execution Debugger (SED) is a debugging and visualization tool based on KeY’s symbolic execution engine that can be used, just like a standard debugger, without any specialist knowledge. Now, the SED has successfully been applied by Aniket Kulkarni from Tata Consultancy Services in the validation of an industrial software component. He concludes that the “SED tool is useful for applying Symbolic Execution techniques as visual feedback is given to the developer”.

New Feature: State Merging in KeY
Current nightly builds of KeY contain a new feature called state merging, a technique to decrease the size of proof trees arising from the symbolic execution of large programs. Continue reading “New Feature: State Merging in KeY”
