Bin Packing Game with an Interest Matrix

چکیده
In this paper we study a game problem, called bin packing game with an interest matrix, which is a generalization of all the currently known bin packing games. In this game, there are some items with positive sizes and identical bins with unit capacity as in the classical bin packing problem; additionally we are given an interest matrix with rational entries, whose element aij stands for how much item i likes item j. The payoff of item i is the sum of aij over all items j in the same bin with item i, and each item wants to stay in a bin where it can fit and its payoff is maximized. We find that if the matrix is symmetric, a pure Nash Equilibrium always exists. However the PoA (Price of Anarchy) may be very large, therefore we consider several special cases and give bounds for PoA in them. We present some results for the asymmetric case, too.

Extending Two-Dimensional Bin Packing Problem: Consideration of Priority for Items
In this paper a two-dimensional non-oriented guillotine bin packing problem is studied when items have different priorities. Our objective is to maximize the total profit which is total revenues minus costs of used bins and wasted area. A genetic algorithm is developed to solve this problem where a new coding scheme is introduced. To evaluate the performance of the proposed GA, first an upper b...
متن کاملBin Packing Games
The bin packing game is a cooperative N -person game, where the set of players consists of k bins, each has capacity 1 and n items of sizes a1, a2, ⋅ ⋅ ⋅ , an, w.l.o.g, we assume 0 ≤ ai ≤ 1 for all 1 ≤ i ≤ n. The value function of a coalition of bins and items is the maximum total size of items in the coalition that can be packed into the bins of the coalition. A typical question of the bin pac...
متن کاملPrices of anarchy of selfish 2D bin packing games
We consider a game-theoretical problem called selfish 2-dimensional bin packing game, a generalization of the 1-dimensional case already treated in the literature. In this game, the items to be packed are rectangles, and the bins are unit squares. The game starts with a set of items arbitrarily packed in bins. The cost of an item is defined as the ratio between its area and the total occupied a...
متن کاملNote on non-uniform bin packing games
A non-uniform bin packing game is an N-person cooperative game, where the set N is defined by k bins of capacities b1, . . . , bk and n items of sizes a1, . . . , an. The objective function v of a coalition is the maximum total value of the items of that coalition which can be packed to the bins of that coalition. We investigate the taxation model of Faigle and Kern (1993) [2] and show that the...
متن کاملA tight lower bound for an online hypercube packing problem and bounds for prices of anarchy of a related game
We prove a tight lower bound on the asymptotic performance ratio ρ of the bounded space online d-hypercube bin packing problem, solving an open question raised in 2005. In the classic d-hypercube bin packing problem, we are given a sequence of d-dimensional hypercubes and we have an unlimited number of bins, each of which is a d-dimensional unit hypercube. The goal is to pack (orthogonally) the...
