A Projection Method for the Integer Quadratic Knapsack Problem

Journal of the Operational Research Society, 1996
Summary: We present a new branch-and-bound algorithm for solving a class of integer quadratic knapsack problems. A previously published algorithm solves the continuous variable subproblems in the branch-and-bound tree by performing a binary search over the breakpoints of a piecewise linear equation resulting from the Kuhn-Tucker conditions.

A note on optimal solutions to quadratic knapsack problems

International Journal of Mathematical Modelling and Numerical Optimisation, 2010
In this note we report our success in applying CPLEX's mixed integer quadratic programming (MIQP) solver to a set of standard quadratic knapsack test problems. The results we give show that this general purpose, commercial code outperformed a leading special purpose method reported in the literature by a wide margin.

A Branch and Bound Algorithm for Integer Quadratic Knapsack Problems

ORSA Journal on Computing, 1995
We present a branch and bound algorithm for solving separable convex quadratic knapsack problems with lower and upper bounds on the integer variables. The algorithm solves a series of continuous quadratic knapsack problems via their Kuhn-Tucker conditions.

Local minima for indefinite quadratic knapsack problems

Mathematical Programming, 1992
The paper deals with the following problem: minimize \(x^ T Dx+d^ T x\) subject to \(\ell_ i\leq x_ i\leq u_ i\;(i=1,\dots,n)\), \(a^ T x=g\), where \(x\in R^ n\), \(D\) is a diagonal matrix, \(d\) and \(a\) are \(n\)- vectors, \(\ell_ 1,\dots,\ell_ n\), \(u_ 1,\dots,u_ n\) and \(g\) are real numbers.

The generalized quadratic knapsack problem. A neuronal network approach

Neural Networks, 2006
The solution of an optimization problem through the continuous Hopfield network (CHN) is based on some energy or Lyapunov function, which decreases as the system evolves until a local minimum value is attained. A new energy function is proposed in this paper so that any 0-1 linear constrains programming with quadratic objective function can be solved ...

A Genetic Algorithm for the Quadratic Multiple Knapsack Problem

2007
The Quadratic Multiple Knapsack Problem (QMKP) is a generalization of the quadratic knapsack problem, which is one of the well-known combinatorial optimization problems, from a single knapsack to k knapsacks with (possibly) different capacities.
