A Hardware Relaxation Paradigm for Solving NP-Hard Problems

Digital circuits with feedback loops can solve some instances of NP-hard problems by relaxation: the circuit will either oscillate or settle down to a stable state that represents a solution to the problem instance. This approach differs from using hardware accelerators to speed up the execution of deterministic algorithms, as it exploits stabilisation properties of circuits with feedback, and ...

Lagrangian Relaxation - Solving NP-hard Problems in Computational Biology via Combinatorial Optimization

This thesis is devoted to two NP-complete combinatorial optimization problems arising in computational biology, the well-studied multiple sequence alignment problem and the new formulated interval constraint coloring problem. It shows that advanced mathematical programming techniques are capable of solving large scale real-world instances from biology to optimality. Furthermore, it reveals alte...

A Graphical Approach for Solving NP-Hard Combinatorial Problems

In this paper we consider a graphical realization of dynamic programming. The concept is discussed on the partition and knapsack problems. In contrast to dynamic programming, the new algorithm can also treat problems with non-integer data without necessary transformations of the corresponding problem. We compare the proposed method with existing algorithms for these problems on small-size insta...

The Sorting Buffer Problem is NP-hard

We consider the offline sorting buffer problem. The input is a sequence of items of different types. All items must be processed one by one by a server. The server is equipped with a random-access buffer of limited capacity which can be used to rearrange items. The problem is to design a scheduling strategy that decides upon the order in which items from the buffer are sent to the server. Each ...
