A number of modern approaches to refinement are discussed and compared, and their broad classification into refinement methods and refinement calculi is explained. The refinement methods concerned are all based on the model-based specification languages VDM and Z, whereas the refinement calculi are all developments of the Dijkstra programming calculus. A generalised comparison of the refinement methods and the refinement calculi is also given.
| citations This is an alternative to the "Influence" indicator, which also reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically). | 5 | |
| popularity This indicator reflects the "current" impact/attention (the "hype") of an article in the research community at large, based on the underlying citation network. | Average | |
