XENO: Computer-Assisted Compilation of Crossword Puzzles
P. D. Smith · The Computer Journal · 1983
XENO is a suite of programs which assist in the creation of crossword puzzles. It is an extension of a diagram filling program presented earlier. Complete puzzles can be produced under the control of a small number of parameters, clues being selected from an indexed file. It is possible to generate thematic puzzles by including keywords in the input parameters. Use of a tree searching method results in a puzzle being generated efficiently.
