reused: result reuse and method reuse. To the former, when the solution in the
base case needs an adaptation, the system looks for prominent differences
between the base case and the target one and then applies a set of adaptation
rules to suggest a solution. The method reuse cares little about the solution
stored in the retrieved case, and reuses the algorithms, or rules employed in
the problem solving in the base cases to produce a new solution to the target
case. In this process, information useful in the base case, such as the can
operation of the operator, consideration of the sub goal, search route of
success or failure, etc., are reconsidered and reinstanced in the target case,
which is also referred to as Derivational adaptation.

Explanation
: Explain the failure in the transformation from solution in the
base case to the generation of new solutions to the target case; provide the
cause-and-effect analysis report. Make explanations in successful cases
sometimes. Explanation-based indexing techniques, which determine relevant
features for each case, analyze each case to find which of their features are
predictive. Cases are then indexed by those features. Indexing based on
explanations an important method too.

are similar to analogical transformation. The input
data for the revise process comprise a proposed solution and a failure report;
sometimes an explanation might also be included. The revise process is to
adapt the input solution to preclude the factors leading to failures.
Case revise happens when the proposed solution is regarded as not good,
so the first step in case revise is the evaluation on the proposed solution. Only
in the cases that the solution is evaluated to be not good, a revise process is
evoked.
The evaluation on a proposed solution can fulfilled on the basis of
feedbacks after the solution's application, or by consulting domain experts. It
takes some time to wait a feedback, e.g., patient's therapeutic effects. The
method of simulation temporal environment is usually employed in solution
evaluations due to the above consideration.
The mistake revise generally involves the mistake finding and the reason
diagnosis. Looking for the reason is for explaining and analyzing the mistake,
in order to find out the reason and suit the remedy to the case, revising the
reason to make the mistake makes it not recur. Certainly, revising can use the
knowledge model of the field to go on mending, can be input and finished by
users too.
