Programming debugging

Therefore my recommended technique is to start with a very small step size to get the program debugged and running. Then make a few quick empirical tests in which you keep doubling the step size. Check the accuracy of successive runs and continue increasing the step size until you find the biggest At that gives sufficiently accurate answers and is stable. 

The book "Algorithmic Program Debugging" by Ehud Shapiro (33) is interesting for its in-depth description of debugging algorithmms written in Prolog. 

For those of you interested in Prolog, the book "Prolog Programming in Depth" (34), has a good discussion of program debugging and verification, as well as an example representation in Prolog of a connectivity table for molecular structure representation.

The stated objectives of the laboratory are to expose the students for demonstrating the basic operations of different data structures, to choose suitable data structure for a given application, to formulate a suitable problem for a given data structure thereby enhancing the programming, debugging, and testing abilities.

The barriers to integration identified earlier in Sections 2.5 and 3.2 will influence the selection of the pilot location. Resistance is often very high for pilot studies—most managers would rather have someone else debug a new program before they have to work with it. This resistance is even more...

Long programs will take hours and even days to write and test. A systematic approach to debugging and verification will reduce this time to a minimum. It will also give you confidence that the numbers are right when they finally are produced. 

The number of radial increments can be picked arbitrarily. A good approach is to begin with a small number, /= 4, for debugging purposes. When the program is debugged, the value for / is successively doubled until a reasonable degree of accuracy is achieved or until computational times become excessive. If the latter occurs first, find a more sophisticated solution method or a faster computer. 

Systematic verification is needed for a program as complex as this. The following tests were made using Itotal = 32. A sequence like this helps in debugging and lends confidence to the final results, although they do not prove...

We have also set up a software library on the 32-bit minicomputer that allows us simulate the diffractometer operation as an aid to developing and debugging programs offline. 

Eiffel is among the few programming languages to provide directly for operation specs, but they can, of course, be documented with an operation in any language. In C++, suitable macros can be used Java could use methods introduced on the superclass Object. For debugging, pre- and postconditions can be executed.
