| Tiivistelmä: | A new approach to evaluate lower bounds for a class of quadratic assignment problems (QAP) is presented. This method could serve as a reduction process to possibly improve the results from a variety of bounding techniques. This approach is tested on two bounds from the literature, the gilmore-Lawler bound (GLB) and an eigenvalue bound (PB), for various problems of size ranging from 6-49. Computational results show a good improvement in bounds for all the test problems. |
