Abstract
The author reports on the performance of a new class of constrained co des, called weakly constrained codes. These codes do not strictly guar antee the imposed channel constraints, but rather generate codewords t hat violate, with a given (small) probability, the prescribed constrai nt. Weakly constrained codes are specifically of interest when it is d esirable that the code rate R = p/q is very high, requiring codewords of length q > 100.
