摘要:
Lower bounds for K(n,R), the minimal number of codewords of any binary code of length n and covering radius R, are improved. The definition of multiexcess is introduced. A technique combining van Wee's method and linear inequalities for covering codes is used. A revised table for K(n,R) (n less-than-or-equal-to 33, R less-than-or-equal-to 10) is given.
