Program Development Tools: Debugging by Reverse Computing

Abstract — More and more program development tools have turned to Web-based. It has an advantage on being a multi-platform tool. This work proposes a debugging tool based on web interface. The main idea of the tool is that the execution of the program can be regarded as a flow. This flow can be captured and played back later. Therefore, any state of the executed program can be analyzed and errors can be pinpointed. We propose a time-reversal computing as a way to capture the flow of execution so that the time step can be reversed without starting from time-zero
