In computer science, symbolic execution (also symbolic evaluation or symbex) is a means of analyzing a program to determine what inputs cause each part of a program to execute. An interpreter follows the program, assuming symbolic values for inputs rather than obtaining actual inputs as normal execution … See more Consider the program below, which reads in a value and fails if the input is 6. During a normal execution ("concrete" execution), the program would read a concrete input value (e.g., 5) and assign it to y. Execution … See more The concept of symbolic execution was introduced academically in the 1970s with descriptions of: the Select system, the EFFIGY system, the DISSECT system, and Clarke's system.
