Here we are going to have a general explanation of how to use the system, what it can do, some things it can't do, etc.
All help pages open in one separate help window, irrespective of them being general (this one), a very specific help page referring to one single parameter, or something in between. This means that if you are looking for help for the second time in one session, the help window can be behindthe one you are requesting help for.
Whenever it makes sense to choose several input values for one single parameter, this is made possible by the use of a multiple choice list. Hold down the <Control> key while clicking on all the values you want to input.
The basic idea of case-based reasoning (CBR) is to draw conclusions out of experience rather than out of analytical knowledge. In other words, reusing know howin absence of know why. To make this possible a large corpus of experience is needed, in the form of parameter values documenting past cases. Each case is thus a self consistent set of parameter values, whereas there is no rule whatsoever relating them.
Faced with a new situation, the CBR system calculates the similarity between the current information and all cases in the database, and it displays the retrieved cases in order of applicability, i. e. the most relevant case in the database is displayed first and so on.
The user chooses the number of cases to be displayed, and the system displays just as many. If the user searches for inconsistent information, the input data will certainly not match any case in the data base. Still, the CBR system is just as capable of calculating which cases are most similar to the information input, sort them and display them.
