A Dynamic Programming Heuristic for the Quadratic Knapsack Problem [PDF]

open access: yesINFORMS Journal on Computing, 2014
It is well known that the standard (linear) knapsack problem can be solved exactly by dynamic programming in 𝒪(nc) time, where n is the number of items and c is the capacity of the knapsack. The quadratic knapsack problem, on the other hand, is NP-hard in the strong sense, which makes it unlikely that it can be solved in pseudo-polynomial time.

PKCHD: Towards a Probabilistic Knapsack Public-Key Cryptosystem with High Density

open access: yesInformation, 2019
By introducing an easy knapsack-type problem, a probabilistic knapsack-type public key cryptosystem (PKCHD) is proposed. It uses a Chinese remainder theorem to disguise the easy knapsack sequence. Thence, to recover the trapdoor information, the implicit

Gradual sub-lattice reduction and a new complexity for factoring polynomials [PDF]

open access: yes, 2009
We present a lattice algorithm specifically designed for some classical applications of lattice reduction. The applications are for lattice bases with a generalized knapsack-type structure, where the target vectors are boundably short.

Translating Constraints into QUBOs for the Quadratic Knapsack Problem

open access: yes, 2023
One of the first fields where quantum computing will likely show its use is optimisation. Many optimisation problems naturally arise in a quadratic manner, such as the quadratic knapsack problem. The current state of quantum computers requires these problems to be formulated as a quadratic unconstrained binary optimisation problem, or QUBO. Constrained

Store-and-forward based methods for the signal control problem in large-scale congested urban road networks [PDF]

open access: yes, 2009
The problem of designing network-wide traffic signal control strategies for large-scale congested urban road networks is considered. One known and two novel methodologies, all based on the store-and-forward modeling paradigm, are presented and compared ...
