features? well, ok. as of the (I swear) final revision (attached here; will also be on my ite space whenever I can access the server): instantrunoff.rar

--it reads ballots in from a file or from command line input. (file format is limited to txt, though.)
--you can vote for as many or as few people on a ballot as you care to. to put it another way, max. votes/ballot is up to you, not me, but you don't have to vote for the maximum.
--no vote is ignored. if your ballot reads MickeyMouse GoofyDog DonaldDuck it'll take that as readily as John Bill Jeff. depending on your point of view, this may not be a feature, but I think write-ins are as American as baseball and apple pie. (Goofy is supposed to be a dog, right?)
--it's verbose. for each round, you see who got the most votes, who was eliminated, and who's left in the runoff.
--it's 93 lines, including liberal commenting.
--it does what it's supposed to.

Update on contest winning entry: Michael, Kevin and Eric, we have not gotten a sponsor for Contest 2 yet, though since we haven't chosen a winner yet, the door is still open. Here's the plan. If we don't get a sponsor by the next GatorJUG meeting, I will choose a prize for the winning entry. I'll continue to search for a sponsor. And, stay tuned for Contest #3! Since all the entries are from GatorJUG members, we'll discuss the conclusion of this contest at the next GatorJUG meeting in March. Sound fair? Let me ask of you that you post the features each of your entries implements here as a comment.

I created an instant-runoff Clojure library, which would be useful for someone who is creating an election application (commandline/web/etc) in Java or any other JVM language. It is only 32 source lines of code, not including the "def candidates" and "def votes" statements which were only used for testing. The winner function takes a list of ballots and a set of candidates as input and returns the winner - a simple and orthogonal API.

http://github.com/ericlavigne/instant-runoff/blob/master/src/electi...

The code was written and thoroughly tested in front of a live audience. Unfortunately those tests were in a Clojure prompt and were lost when my laptop batteries died. I have started rebuilding the test suite, as shown in the following file.

Since I was out of town for the March meeting, let's get together at the April meeting (at the Civic Media Center) to determine a winner.

My project just ran for real. Some of the students are fussing. It is interesting to read some of thier posts.

We had 4 parties.
two obviously lost and two where very, very close for winning. The party that had the most number one votes then lost because the party in second place had the most second and third place votes.

very interesting.

Congrats Dan!

Some people are upset about losing, and the new system is an easy scapegoat. Still, even in the losing party there are people saying to stop being so childish. Sounds like it went well.

I have had projects blow up in my face for having mistakes in them before. I have never had one blow up because it was done properly.
Pretty funny really.
