Picking sequences for the allocation of indivisible goods

Picking  sequences  are  a  natural  way  of  allocating  indivisible  items  to  agents  in  a
decentralized manner: at each stage, a designated agent chooses an item among those
that  remain  available.

The main problem consists in choosing the “best” sequence of agents,  according to some optimality criterion.
We  assume  that  agents  have  additive  preferences over  objects.   The  choice  of  an  optimality  crite-
rion depends on three parameters:  how utilities of objects  are  related  to  their  ranking  in  an  agent’s
preference relation; how the preferences of different agents are correlated; and how social welfare is
defined from the agents’ utilities.  We address the computation  of  a  sequence  maximizing  expected
social welfare under several assumptions.  We also address strategic issues.
