WebNonetheless, due to the limit from the underlying symbolic execution engine, i.e., CUTE [11], this method requires the availability of source code. Driller [12] takes advantage of a similar idea as [10], where the main exploration is ofﬂoaded to fuzzing and concolic execution is only invoked if its input reasoning ability is Webusually supported by state-of-the-art symbolic execution engines. There are at least two sides to our project, creating an adequate platform for symbolic execution (next section) and developing the actual execution engine (last section). 2 INFRASTRUCTURE The original version of selfie was 32-bit, used signed integers and

KeY operates on the source code level and thus a static symbolic execution is performed meaning that the program is never actually executed. KeY\'s Symbolic Execution Engine constructs a proof and extracts the symbolic execution tree from it. gutbrod hb 48 4 0 hp
