  Abstract:
  The binary quadratic knapsack problem has been intensively studied over the last decades. Despite most of real-world problems are of a multi-dimensional nature there is not a considerable body of research for multi-objective binary quadratic knapsack problems, even in the case when only two objective functions are considered. The purpose of this paper is twofold: First, it aims at giving some insights on the bi-objective quadratic knapsack problem in order to solve it faster by building adequate heuristics and bounds for being used in approximations methods; and, second, to study a new linearization that involves less constraints than the existing ones. This paper addresses thus the bi-objective binary quadratic knapsack problem and proposes new algorithms, which allow for generating the whole set of exact nondominated points in the objective space and one corresponding efficient solution in the decision space. Moreover, this paper proposes a new linearization of the binary quadratic knapsack problem, which appears, on average, to be faster than the existing ones for solving the single and bi-objective quadratic knapsack problem. Computational results are presented for several types of instances, which differ according to the number of items or variables and the type of correlation between the two objective functions coefficients. The paper presents thus a comparison, in terms of CPU time, of four linearizations over several types of 30 instances of the same type and size.
