An Algorithm for Computing the Minimum Distances of Extensions of BCH Codes Embedded in Semigroup Rings

An algorithm is given for computing the weights of extensions of BCH codes embedded in semigroup rings as ideals. The algorithm relies on a more general technical result of independent interest.
