Talk:Bulls and cows/Player

When I wrote the original scorer task Bulls and cows I vaguely remembered that I had written a player before, in a dialect of basic, probably in the late, late eighties. Well, I was ignoring what I was supposed to be doing this weekend and just started doodling a solution and it seemed to gel.
With possible answers being restricted to a selection of four digits from the nine,
- I generate the 3024 possible initial choices (and randomly shuffle them).
- Select the first choice as my next answer,
- Then get its score.
- Next, whittle down the possible choices by removing from the choices any choice where if it where the true answer, it would not give the score I had just received.
- Repeat from 2.
If I get all bulls then I win. If there are no more choices then the scores must be inconsistent.

- My conversion of that code (for the Tcl version) does one key thing differently; instead of shuffling the values it picks a random one. Simpler to implement. –Donal Fellows 08:43, 14 June 2010 (UTC)
