I belonged to an Alvey project called Adaptive Intelligent Dialogues
in which we investigated Adaptation.  During the course of this 4 year
project we produced a taxonomy of adaptive systems.  This is
reproduced below.  The levels refer to the 'level of adaptivity' with
corresponding meanings in the computer world and w.r.t. evolution.

Much of this work was done by Pete Totterdell (pc1pat@ibm.sheffield.ac.uk)
see; Totterdell, P.A.; Norman, M.A and Browne, D.P.; "Levels of
adaptivity in interface design"; HCI Interact'87, 1987, pp 715-722.

Also the project (which finished October 1988) is producing a book on
this subject and further information can be obtained from Prof. Mike Norman
Hull University, Hull, England. (mike@isdg.cs.hull.ac.uk)
