I'm looking for an explanation of the Kameda-Weiner algorithm.
I found the paper "On the State Minimization of Nondeterministic Finite Automata" which, I assume, contains this, though it's unfortunately behind a paywall, and I'm just a hobbyist.
Can someone explain the algorithm, or point me to another source?
Although I have absolutely no idea what you are talking about, I think these two pdf files contain some sort of explanation.

I just tried to answer it, because I know how frustrating it can be, when you something you really want is behind a paywall! Hope it helps.
Cheers!
It's implemented here: https://github.com/coder0xff/parlex_legacy/blob/132e4a23a599140d22b18ead832626f0c607340f/Automata/NFA.cs#L641

I was just browsing http://plugins.netbeans.org/PluginPortal/
I like the way that the table at the bottom of the page works, with its various live filtering & sort options. Particularly its speed, fluidity & function.
Does anyone know how this would have been implemented (I'm talking specifically, I have a good understanding of the generalized process, and am interested in the specific technology if it already exists as a particular type of control in/on a particular platform)?
Your help would be greatly appreciated.
looking at the page source it looks like the DataTables plug in for jquery see here

I have no idea, I Googled, no dice.
In context: "Do we have an LOE on this? They keep asking me haha. :)"
I have googled and googled and googled and can't put my hands around it. Could someone explain it to me like I'm five?
Level Of Effort is the most likely one. There are a bunch listed here as well: http://www.acronymfinder.com/Business/LOE.html
I guessed this one because it was in the context of project management, and that's the type of thing a PM needs to know.
And it specifically shows up here: http://www.all-acronyms.com/LOE/tag/project_management as the first Google result of a search for "LOE project management acronym"

I am testing/searching tests for my image manipulation algorithm and I have come across to "lena.png" multiple times. Why? Is it some kind of standard algorithm testing picture? I would like to know the history behind the picture.
Is there other similars pictures I could use? Why?
