Hi,
I just remembered that just pressing the "respond" button doesn't work
with this list, because you also have to change the address, so sorry Frank,
you read the following already... OK, now for the message:
I used it to generate a Minimum Spanning Tree out of a given graph...
of course an application without real use, I just did it to
demonstrate it worked and was portable. I had a graph like this:
O--O
|\/|
|O |
|/\|
O O
(with the Os representing vertices, and the lines edges. The edges
were numbered so I they'd be distinguishable.) I had the
user press a button any number of times for every edge, so it would
have an associated weight. Then I simply compiled the result using
Kruskal's algorithm and displayed the number of the 4 chosen edges
(for an interconnected graph with n vertices, a MST generator chooses
n-1 edges). It was for a school project, and I got an A for it. Also
ported it to my calculator... was great fun. I still have the .nqc
file somewhere.

| Hello, Over in k12.ed.science a poster wanted to perform an experiment where he would time how long it took various objects to fall when dropped inside a long tube. He was looking for information regarding timing circuits, how to build one, where to (...) (23 years ago, 19-Aug-01, to lugnet.robotics.rcx)
