TL;DR: In this article, a binary branch and bound algorithm for the exact solution of the Koopmans-Beckmann quadratic assignment problem is described which exploits both the transformation and the greedily obtained approximate solution described in a previous paper by the author.
Abstract: In this paper a binary branch and bound algorithm for the exact solution of the Koopmans-Beckmann quadratic assignment problem is described which exploits both the transformation and the greedily obtained approximate solution described in a previous paper by the author. This branch and bound algorithm has the property that at each bound an associated solution is obtained simultaneously, thereby rendering any premature termination of the algorithm less wasteful.

TL;DR: This work extends a classical single-machine due-window assignment problem to the case of position-dependent processing times, and introduces an O(n3) solution algorithm, where n is the number of jobs.
Abstract: We extend a classical single-machine due-window assignment problem to the case of position-dependent processing times. In addition to the standard job scheduling decisions, one has to assign a time interval (due-window), such that jobs completed within this interval are assumed to be on time and not penalized. The cost components are: total earliness, total tardiness and due-window location and size. We introduce an O(n 3) solution algorithm, where n is the number of jobs. We also investigate several special cases, and examine numerically the sensitivity of the solution (schedule and due-window) to the different cost parameters.

TL;DR: It is shown that the CVM3 problem is NP-complete and a heuristic algorithm is proposed and the experimental results show that the proposed algorithm is efficient and generates fairly good solutions.
Abstract: The layer assignment problem for interconnect is the problem of determining which layers should be used for wiring the signal nets so that the number of vias is minimized. The problem is often referred to as the via minimization problem. The problem is considered for three-layer routing, concentrating on one version called the constrained via minimization (CVM3) problem. It is shown that the CVM3 problem is NP-complete and a heuristic algorithm is proposed. The experimental results show that the proposed algorithm is efficient and generates fairly good solutions. >
