The following two important aspects of multilevel static memory management are treated: (1) memory loading, and (2) memory sizing. An algorithm is developed for the optimal loading of program and data files in various memory levels of given sizes. The selection of optimal sizes from a given set of finite alternatives is done through a cyclic queueing model,(More)
Software testing is a well-defined phase of the software development life cycle. Functional ("black box") testing and structural ("white box") testing are two methods of test case design commonly used by software developers. A lesser known testing method is risk-based testing, which takes into account the probability of failure of a portion of code as(More)
