A physicist's approach to number partitioning | Stephan Mertens
; | Date: |
15 Sep 2000 | Subject: | cond-mat | Affiliation: | Otto-von-Guericke Universität, Magdeburg | Abstract: | The statistical physics approach to the number partioning problem, a classical NP-hard problem, is both simple and rewarding. Very basic notions and methods from statistical mechanics are enough to obtain analytical results for the phase boundary that separates the ``easy-to-solve’’ from the ``hard-to-solve’’ phase of the NPP as well as for the probability distributions of the optimal and sub-optimal solutions. In addition, it can be shown that solving a number partioning problem of size $N$ to some extent corresponds to locating the minimum in an unsorted list of $igo{2^N}$ numbers. Considering this correspondence it is not surprising that known heuristics for the partitioning problem are not significantly better than simple random search. | Source: | arXiv, cond-mat/0009230 | Services: | Forum | Review | PDF | Favorites |
