This might give all voters an incentive to give sincere ballot information, since that would be the safest individual strategy.</font></div></div></span></blockquote><div><br></div><div>That's an interesting approach. Maybe one should have some concrete proposals to be able to compare the benefits and the problems. The resulting randomness means in principle some deviation from picking the best winners, and some of the original strategies might still be usable (voter picks a strategy that improves the results with one method and is not too bad in the other method), but if the method is well planned the benefits may be bigger than the problems and added complexity.</div><br><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div bgcolor="#ffffff" style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div><font size="2" face="Arial"></font> </div><div><font size="2" face="Arial">Alternatively, the threat of assigning all offices by lot might be used as a stick to prompt all voters to come to a unanimous agreement using an iterative or "bidding" process.</font></div></div></span></blockquote><div><br></div><div>Yes, if the resulting level of randomness is acceptable in the results.

There could be also preferences like "I want a room next to my closest colleagues". If one wants to support also such preferences one could allow the voters to rank all the possible room allocation scenarios and then use some Condorcet method to pick the best allocation. Since the number of different room allocations may often be too large for manual ranking one would need some mechanism to derive the rankings from some simpler set of parameters. One could e.g. use a fixed questionnaire with a list of questions that the voters could answer and give different weights. These answers could then be used to rate each room allocation scenario. In theory one could also allow voters to give their own algorithm (this is however probably too complex though for most use cases) that takes a room allocation scenario as input and rates it (or gives directly a ranking of all the allocations (or why not even pairwise preferences (that could lead to personal preference cycles))).</div><div><br></div></div><div><br></div><div><br></div><div><div>On Jan 23, 2010, at 5:37 PM, Michael Rouse wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div text="#000000" bgcolor="#ffffff">Steven E.

Have room locations across the top (x-axis) and people’s names down the left (y-axis). Each professor could rank the rooms in order of their own preference, and rank the potential occupant in each room in order of preference, all on one handy grid. People could then trade their votes (or something more tangible for votes) in order to get the room they want. On a certain date, finalize the votes, determine the allocation of rooms to maximize overall satisfaction, and start moving in.</p><p><br>It might be difficult to find the peak utility order (probably NP-hard), but it should be manageable — you probably don’t have to worry about hundreds of professors, and that’s what computers are for.
