Open Source Java Voting Software

Belief merging aims at combining several pieces of (possibly inconsistent) information coming from different sources. The goal is to produce a single consistent set of information, trying to keep the most of the information of the sources. A belief merging operator is the responsible for making the belief merging. With this tool you can compare the ΔΣ, ΔGMax and the Δps (PS-Merge) operators.

Belief revision is a central topic in knowledge representation and reasoning. It consists in incorporating a new belief, changing as few as possible of the original beliefs while preserving consistency. Revision always considers new evidence as a better belief. Such new evidence is usually represented in the form of a propositional formula which must be preserved after the revision. Here, the Δps (PS-Merge) belief merging operator is extended in order to consider constraints, and this extension is used as a strategy for belief revision. The new evidence is treated as a constraint so the extended merging operator can obtain the revised belief base.

VoteCounter is a distributed voting program which can handle multiple clients over a network. VoteCounter is written in Java, and so it is very portable; VoteCounter's input is an XML file specifying posts to be voted for and nominees contesting them, and it's output is a human-readable tally of votes for each nominee, making it easy to use and customize. VoteCounter is still under development, but is ready to use for small elections. Help is welcome! VoteCounter is authored by Shardul C.
