Abstract
An O(n(2)L) time and O((n + k)L) space algorithm is provided for decid ing whether or not a finite set C consisting of n words having total l ength L, where all words are taken over a k-element alphabet, is a mul tiset decipherable code. The algorithm is based on a technique related to dominoes. At an early stage it decides in O(nL) time and O((n + k) L) space whether or not set C is uniquely decipherable.
