The problem of finding good covering codes in Hamming spaces is considered. Many different local search methods have been used to find packing codes (the dual problem), whereas practically all published results on searches for covering codes are based on simulated annealing. In this article tabu sea
A simple way of as,;ociating a matroid of prescribed rank with a graph is shown. The matroids so corhstrueted are re.presentable over any sufficiently large field. Their ase is demonstrated by the fallowing result: Given an integer k >~ 3 and a hmction G associating a group with each subsel of a set
