Web19 de ago. de 2024 · In particular, we study two algorithms that are known to produce such allocations in the non-strategic setting: Round-Robin (EF1 allocations for any number of agents) and a cut-and-choose algorithm of Plaut and Roughgarden [SIAM Journal of Discrete Mathematics, 2024] (EFX allocations for two agents). WebMMS allocations [10], EF1 allocations for chore division [12], approximate EFX allocations [34], and partial EFX allocations (\EFX with charity") [19], among several others. ... the number of unallocated items strictly decreases with every operation (1).

Computing welfare-Maximizing fair allocations of indivisible goods

Web29 de mar. de 2024 · However, in any EF1 allocation the last two goods cannot both be given to agent 2. Hence the social welfare of an EF1 allocation is at most (1/3 − 2 𝜖) + (1/3 + 𝜖) + 1/2 = 7/6 − 𝜖. Taking \epsilon \rightarrow 0, we find that the price of EF1 is at least \frac {4/3} {7/6} = 8/7. We now turn to the upper bound. WebWe consider the classic problem of fairly allocating indivisible goods among agents with additive valuation functions and explore the connection between two prominent fairness notions: maximum Nash welfare (MNW) and en… the paletas little italy
