WebOct 8, 2024 · We describe a binary (17,4,5) constant weight code with 444 codewords, thus improving the lower bound for A (17,4,5) from 441 to 444. The code was discovered by a computer search implementing a new stochastic local search algorithm for the maximum independent set problem. WebA general theorem is proved showing how to obtain a constant-weight binary cyclic code from a p-ary linear cyclic code, where p is a prime, by using a representation of GF(p) as cyclic shifts of a binary p-tuple. Based on this theorem, constructions are given for four classes of binary constant-weight codes. The first two classes are shown to ...
