Device, system, and method for automatically detecting and repairing a bug in a computer program using a genetic algorithm

A computing device, comprising:

• a processor;
• and
• a memory having instructions stored thereon which, executed by the processor, cause the processor to perform:
• testing a response of an original computer program using a fuzz tester with initial test variables until a faulty response is detected;
• providing the initial test variable determined by the fuzz tester to cause the faulty response of the original computer program due to a bug within the original computer program to a computer program repairer;
• testing computer program candidates that are separate and functionally equivalent to the original computer program with the computer repairer using a suite of test variables including the initial test variables;
• and
• modifying and selecting the computer program candidates using a genetic algorithm based on results of the testing to produce bug-free computer program candidates that are functionally equivalent to the original computer program.
