One of my interest is finding sparsity in large sets so that it can eventually be detected using compressive sensing. An example of that for instance is bugs in software as shown in this paper:
http://arxiv.org/abs/0905.2288 as mentioned in
http://www.technologyreview.com/blog/arxiv/23548/<p>I have seen several times, that in order to catch errors, some folks seem to go through what I have seen defined as unit testing. With programs getting larger and larger, one is obviously looking at a combinatorial process eventually (which would explain why there would be more errors in larger codes, as they are harder to find in very large sets) Does anybody have a reference where this type of testing is described ?
