here enclosed five files:
- one to explain you the 'triangle' : every summit of the triangle is a
possible stage of the 4-disks Tower of Hanoï. The corresponding positions
of disks are noticed. The triangle is the tree of all possible states of
the problem.
every litle side of triangles is a possible move which allow to go from a
stage to another
- a second file shows a partition of this triangle into four parts. Each of
them regroups a subset of the possible states which have some specific
common properties:
S1 and S4 are near the optimal strategy since S2 and S3 are far away
S1 and S2 before the first move of disk 4 since S3 and S4 after
S1, S2 and S3 before disk4 has reached peg-C for the first time since S4 after
- a third file shows the different possible summits corresponding to the
fact that an essential subgoal is achieved. That is when the position of
disk3 went for the first time into the good position which allows disk4 to
go in C; when disk4 reached the peg-C for the first time, and then when
disk3 went on disk4 for the first time
But of course there are different possible summits according to such or
such specific strategy
- another point to be considered concerns the different batches
of 2-top-disks moves which allow the move of disk 3 or of disk 4.This
concept is more difficult to understand because it is closely linked to a
specific strategy.
The file BUTSLOTS shows the example of a specific strategy for which
essential goals and also the different batches of moves are noticed.
- at last a recapitulation of the different definitions is in the file Invokvar
Some others property linked to the spreading and reconstruction of 2-disks
pyramids and to the different possible geometrical configurations of the
strategy into the triangle has to be considered. But I prefer to explain
them another time because it is also a litle complicated.
All these properties of the current state of the problem were characterized
at first from the results of the verbal protocol analysis.
But their identification independant from verbal analysis allows now to
characterize the contextual effects in term of physical properties of the
current state. So that linguistic contexts can be directly matched to
patterns of these physical properties. So I think one have to consider them
in the coding of statements in order to improve the analysis of verbal reports.
All that is perhaps a litle complicated. I don't know if I am clear in my
explications. If not I will try to give you other examples.
I will continue next week.
Yours
Josiane
