Add to ORKGWe present QUIPSTER, an experimental system for the automatic solution of short substitution ciphers (Cryptoquotes). The system operates using an -gram model of English characters and stochastic local search over the space of ¡£¢¥¤§¦©¨��������� � possible keys. Experimental results show a median of 94 % cipher letters correctly decoded, which is typically good enough for an unskilled human to finish decoding the cipher with minimal additional effort. Extensions incorporating a dictionary with word frequencies and a database of word patterns are also discussed.
