Acm algorithmic debugging dissertation distinguished program
Algorithmic debugging also called declarative debugging is a debugging technique that compares the results of sub- computations with what the programmer intended.
The technique constructs an internal representation of all computations and sub-computations performed during the execution of a buggy program and then asks the programmer about the correctness of such computations. By asking the programmer questions or using a formal specification acm algorithmic debugging dissertation distinguished program, the system can identify precisely where in a program a bug is located.
Debugging techniques can dramatically reduce the time and effort spent on debugging. Program debugging is an extremely common acm algorithmic debugging dissertation distinguished program of software development.
Algorithmic program debugging
Until the s the craft of program debugging, practiced by every programmer, was without any theoretical foundation. Acm algorithmic debugging dissertation distinguished program acm algorithmic debugging dissertation distinguished program, a bug occurs when a programmer has a specific intention regarding what the program should do, yet the program actually written exhibits a different behavior than intended in a particular case.
One way of organizing the debugging process is to automate it at least partially via an algorithmic /book-binding-services-reading.html technique. It does so by asking the programmer about possible bug sources. The algorithmic debugging technique constructs an internal representation of all computations and sub-computations performed during the execution of a buggy program an execution tree.
Then, it asks the programmer about the correctness acm algorithmic debugging dissertation distinguished program such computations.
Algorithmic program debugging - Wikipedia
Some algorithmic debuggers also accept the answer "I don't know" when the programmer cannot give an answer e. Thus, the answers of the programmer guide the search for the acm algorithmic debugging dissertation distinguished program until it is isolated by discarding correct parts of the program.
The algorithmic debugging process finds one bug at a time. In order to find different bugs, the process should be restarted again for each different bug.
Shapiro source the method of algorithmic debugging in Prolog [4] a general purpose logic programming language for the debugging of logic programs.
In case of logic programsthe intended behavior of the program is a model a set of simple true statements acm algorithmic debugging dissertation distinguished program bugs are manifested as program incompleteness inability to prove a true statement or
Acm algorithmic debugging dissertation distinguished program method to handle non-termination was also developed. The research and development in the field of Algorithmic debugging has made major improvements over the original algorithms for debugging Prolog and click at this page and extended the ideas to other language paradigms such as functional languages and object oriented languages.
