HFFD Algorithm Input

Important: Identical-Order Preference (IDO)

The HFFD algorithm requires that all agents agree on the relative ordering of items by cost. This means:

  • If one agent considers item A more costly than item B, all other agents must also consider A more costly than B
  • The actual costs can be different for each agent, but the ordering must be the same
  • This property is essential for the algorithm to work correctly

Valid Example (IDO):

Agent 1: [5, 3, 1] (5 > 3 > 1)

Agent 2: [10, 6, 2] (10 > 6 > 2)

Agent 3: [2.5, 1.5, 0.5] (2.5 > 1.5 > 0.5)

Invalid Example (Not IDO):

Agent 1: [5, 3, 1] (5 > 3 > 1)

Agent 2: [1, 6, 2] (1 < 6 > 2) - Different ordering!
