Sorry this
is a bit late...the fourth of July and all happened (like it usually
does). This week went rather well. Dr. Wagstaff came to visit
Dr. desJardins and sat in on our meeting. Since I was to work
on the clustering portion of the program this week, Dr. Wagstaff
kindly offered me some examples of implementing the algorithm
and even the actual code!
It took me
a while to get used to implementing the code for COP-kmeans clustering,
since there was the added complexity of the user moving the nodes
*not* in the order in which they were read. After the manipulation
of some counter arrays and such, I got it working. I was so happy!
It was working perfectly...except for one thing, which I don't
even remember now.
So of course,
I set about fixing it. Guess what! I completely (for lack of a
better word) screwed up the program. I had no idea what I changed
or anything. So I decided to revert to an older version of the
program, that I backed up. Well, for some obscure reason, this
program was a mirror of the one that I had just written. So I
started completely over (before implementing COP-kmeans). Infuriating.
It's working to almost the same standard that it was before.
For a time,
I thought that I'd back away from my completely screwed version
of the program, and concentrate on creating the nodes for the
cluster centers. Wouldn't you know that doing that would be even
more problematic?
Here's the
issue: So I can add a node to the graph fine. No problem whatsoever.
But I need to add edges and fix coordinates, which apparently
is *not* fine. I can do this if I enter the graph manually (I
checked), but I can't if I read the graph in through a file. I
just haven't figured it out yet. I guess that's what next week
is for.
In Other News:
I took Amtrak down to Newsport News (NPN) to visit with my grandparents,
aunt and uncle, and cousins for the fourth of July. Taking the
train was a lot of fun, since I had never done that alone before.
I was really nervous, but I figured, hey, I can't get lost! The
fourth was a lot of fun, even though I missed my sister's birthday
(Happy Birthday Suzi!). I was glad to see my family, who I hadn't
seen in about a year and a half. Hopefully I'll be going back
again soon, since it's so close.
