1. in LINK: Graph View, there is a menu called Graph-View, when I draw
a graph, then click the redraw, after a while, there will blick once,
then nothing all happened, and also when I click the refresh graph,
nothing all happened, I think it is because I do not know how to use
it. can you tell me?
2.on LINK: graph view, there is a menu Layout, under Layout, there is
Edge Draw, I tried, but it seemed it has no effect on the picture,
perhaps I am wrong in using it. can you tell me how I can use it correctly?
3. when I tried the web example (An example Scheme/Tk session(which sets
edge weights, finds a minimum spanning tree...), I have the error:
STk> (define g (graph *link:selected-graph-view*))
*** Error:
unbound variable: make-graph
I do not know why?
4. now I have already finished reading all the examples on the web,
and I have some questions.
A: in "Graph Drawing and Manipulation with LINK"
I tried the Figure3.
first I draw the graph, then I typed:
STK>(describe (graph (current-graph-view)))
*** Error:
unbound variable: make-graph
why?
B: I tried figure 4 and figure 5, all only I have just the result
for example: ....val={{1 2} {2 3}}
(38.0 13.0)
, How I can get the graph of it ?
C: about the figure 6, which is abou the Binding the "f" key
so that the forefather of a selected vertex is flashed.
I typed all the stk code, then the result is just:
#undefined, how I can see its use on interface?
aslo in articel:
Improving Discrete Mathematics and Algorithms Curricula with LINK.
I tried the figure 3: A random walk function,
I also typed the code, also the result is #undefined,
I can not see any interface which illustrated this randow walk, How I
can see it from the LINK GUI?
D:
about the Latka Tournaments, because I lack some knowledge about the
discrete mathematics, I see some book, but some concepts I still
do not understand, I am not clear about the useage of this Latka
tourment, in real world, what is the detail advantage of this Latka
Tourment.
I have some other questions about articles. I will summary it and send
E-mail to you later.
Thanks!
