Move–to–front method (MFT):

After the required record is sited, keep that at the head of the list.

Transpose method:

Count method:

Ordering the self-organizing list by number of times the records are being processed.

Ordering method:

Ordering the self-organizing list by using definite criteria for information under analysis.

Explanation of Solution

(b) Cases in which the methods need an exhaustive search of the lists for every search:

A list “L” is searched exhaustively by the move to front method while searching for its last record. This needs the data to be composed in the same sequences of records as in the list “L”, however in the reverse order. For instance, if the list
L = (p x r y) then the data sequence has to be (y r x p y r x p y r x p y…)...
