When a “node” concept is accessed only the “visited” attribute is updated (set to 100) and the knowledge is “collected” from the children concepts.
The meaning of the “generic” condition
Desirability of the concepts for analytic user
Concept at the level lower than “up to” level is desirable if:
Concept is the first child of it’s parent and the parent is visited (the value of the “visited” attribute is used & not “knowledge” because the parent concept is of a “node” type. When this concept is accessed it’s knowledge is not increased. The concept will “collect” the knowledge from it’s children).
Concept is not the first child of a parent & the knowledge about the previous sibling of this node in the parent's children array (variable “previousSibling” in the strategy description) is greater some threshold, for example 75 & the previous sibling has been visited. The threshold is provided by the author.
2. Concept at “up to” level or at the level greater than “up to” is desirable if:
The predecessor concept at the level above “up to” level is read.
Desirability of the concepts for global user
Concept at the level lower than “up to” level is desirable if:
all the concepts at the above level are visited
2. Concept at “up to” level or at the level greater than “up to” is desirable if:
All the concepts at the level above “up to” level are visited (at level “personal.upToLevel-1”)
If the user’s style is not known all concepts are suitable.
