Crossword Puzzle Generation Algorithm

Click For Summary

Discussion Overview

The discussion revolves around the challenge of implementing a crossword puzzle generation algorithm for a dictionary app. Participants explore strategies for efficiently finding intersecting words from a given list, focusing on avoiding complex control structures like loops and genetic algorithms.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant expresses difficulty in finding intersecting words without using extensive loops and seeks an inexpensive strategy for procedural generation.
  • Another participant suggests using regular expressions to search the dictionary word list, although this is seen as merely abstracting the looping process.
  • A different viewpoint proposes pre-processing the word list by storing words in a database with attributes such as word length and known letters to facilitate efficient querying.
  • One participant questions the necessity of using goto statements and suggests a recursive backtracking algorithm as a potentially more efficient approach.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the best approach to the problem, with multiple competing strategies being proposed and debated.

Contextual Notes

Some limitations include the need for pre-processed data and the potential inefficiency of certain algorithms, which remain unresolved in the discussion.

Who May Find This Useful

Developers and programmers interested in algorithm design, particularly in the context of game development and word puzzles.

Hey all, for a dictionary app I have to code I have to implement as crossword game as a side feature, unfortunately this is compulsory, I can't figure out a good way of finding words that intersect each other (esp words that intersect multiple others) without a hell of a lot of goto and while's. Is there a good, inexpensive strategy (so no genetic algorithms or pure bruteforce) given a list of words, to find good intersections to procedural generate the crossword without while loops that may not even be guaranteed to resolve themselves? Any help appreciated.

Thanks but that's just abstracting the loop, I'm certain the key lies in pre-processing the data.
 
You could, of course, put all the words in a database:
  • Word
  • Dictionary entry
  • Word length
  • First letter
  • (Second letter etc.)
Now you have pre-processed the data. In order to find the word you want, create a query incorporating the word length and known letters...

Transform code to produce a crossword (7 letters).
