Given n items with different sizes si and profits pi, m knapsacks with different capacities cj and a restricted bipartite graph G =(S ∪ T, E), where each vertex ui in G presents an item i, and the two items i and j may be packed into same knapsack only if the two vertices ui and uj are adjacent in G, and for 1 ≤ k ≤ m, the profit of each knapsack bk is defined as the total profit of the items packed into the knapsack bk, we study two variants of the multiple knapsack problem with restricted bipartite graph (MKPBG) as follows: (i) the objective is to maximize the total profit of items packed in these m knapsacks (Max-Sum MKPBG, for short);(ii) the objective is to maximize the minimum value of m profits among these m knapsacks (Max-Min MKPBG, for short).
