When looking at science and technology today, we find a recurrent problem to many fields: <i>how to cover a search space consistently and uniformly</i>. This problem is encountered in robotics (searching for targets), optimization (searching for solutions), mathematics and computer science (graph traversals), and even in software engineering (the main(More)
Like in other fields, computer products (applications, hardware, etc.), before being marketed, require some level of testing to verify whether they meet their design and functional specifications -- called <i>functionality test</i>. The general process of performing functionality test consists in the production of a <i>test plan</i> that is then executed by(More)
The relationship between chronic gastritis and peptic ulcer was studied in 97 patients, 51 with duodenal ulcer and 46 with gastric ulcer.
