This description is misleading. It omits that there are no known good
algorithms for implementing this method: the computational complexity
of Dodgson's voting method is prohibitive. In fact, it was not even
known until a few years ago, when the problem was shown to be complete
for parallel access to an NP oracle (class Theta_2^p).<br>

This result means it is extremely far from being usable in practice.
Unless P=NP, there are no polynomial-time algorithms for deciding
elections with Dodgson's method.<br>

-- Andrew<br><br></div></blockquote><div>Huh? Dodgson's method is asset voting. If I'm not mistaken, he did not put any time limit on the convention - vote holders could refuse to delegate their votes. Other Asset systems mandate vote transfers under certain circumstances (elimination-style, to prevent games of chicken of "you endorse me", "no, you endorse me"). However, in either case, it's still a decidable process.<br>
<br>If you want tweaks to Asset to promote dialog: you can mandate some form of accessibility to communication, either vertically (between a voter/proxy and their proxy/metaproxy) and/or horizontally (between the voters/direct subproxies for a given proxy). I think that vertical accessibility to communication should be mandatory, and all vertical communication should be accessible (though perhaps anonymized) horizontally. This would mean that every level could function as a deliberative body.<br>
