....Adaptation With routine problem solving tasks, the retrieved case, will probably require more substantial modifications. If we allow to change the structure of the solution during adaptation we speak of structural adaptation. Structural adaptation [Goel and Chandrasekaran, 1989, DRAFT Smyth and Keane, 1996] supports the reorganisation of solution elements and permits the addition and deletion of such elements under certain conditions. Also structural adaptation systems employ a fixed set of adaptation operators and or transformation rules which modify the structure of the solution, depending on ....

....solving problems from scratch with little use of prior experience. In contrast, case based reasoning (CBR) systems try to make use of past experience during problem solving. CBR systems deploy case bases of previously solved problems to tackle new problems (see, e.g. 19] 30] 31] 32] [33], 34] 35] 36] When a new problem is encountered, it is used as a probe to retrieve a similar problem case from the case base. The solution for this case is then modified or adapted to fit the target problem (see, e.g. 11] 12] CBR systems can also learn by storing the results of a ....

The case base is made up of abstract cases (offering high level rough designs) and concrete cases (containing executable plant control code) HCBR ....

.... how can complex new problems be broken up into simpler sub problems which can be solved by the retrieval and adaptation of individual cases The paper reports on a novel technique called hierarchical case based reasoning (HCBR) used in a software design system called D j Vu ( 28] 29] 30] [31]) D j Vu solves complex plant control (PC) software design problems by reusing multiple cases at varying levels of abstraction. Plant control software designs are stored, not as single cases, but as hierarchies of cases. These hierarchies are made up of abstract cases (offering high level ....

....as new sub problem specifications, and result in the retrieval and adaptation of additional cases. The following sections will refer to the retrieval and adaptation of cases within HCBR. Unfortunately these topics lie outside of the scope of this paper. However, further information can be found in [31] and [32] 5.1 The Main HCBR Algorithm Hierarchical case based reasoning adds complexity to the standard CBR model, since problem solving is now an iterative process whereby many cases are retrieved and adapted, problems are decomposed, and new solution components are integrated into an evolving ....
