<div dir="ltr"><div><div><div><div><div><div><div>This method requires complete preference ballots: no equal ranking nor truncation allowed. However it could be adapted to other types of ballots including range ballots in various ways.<br>
<br></div>Method:<br><br></div>Let N be the number of candidates. On every ballot insert approval cutoffs in the N-1 spaces between the ranks. <br><br>Find the approval winners for each of the cutoffs. <br><br>Eliminate every candidate that is not an approval winner for any of the N-1 cutoffs.<br>
<br></div>Find the new ranks on each ballot for the remaining candidates.<br><br></div>Repeat the process, until only one candidate remains.<br><br></div>I call this method "safe elimination" because, unlike superficial IRV, it sounds the depths of the ranks at every stage of the elimination.<br>
<br></div>I am confident that the Yee diagrams of this method will exhibit none of the pathologies that the Yee diagrams of IRV reveal. And unlike Borda, it does satisfy the Majority Criterion.<br><br></div>However, I do not believe this complete rankings version to be clone free or burial resistant, let alone monotonic. So at this stage it is just an interesting idea meant to stimulate the imagination more than anything else.<br>
