Documentation.SBV.Examples.Queries.GuessNumber
Description
A simple number-guessing game implementation via queries. Clearly an SMT solver is hardly needed for this problem, but it is a nice demo for the interactive-query programming.

guess :: Integer -> Symbolic [Integer] Source #
Use the backend solver to guess the number given as argument.
The number is assumed to be between 0 and 1000, and we use a simple
binary search. Returns the sequence of guesses we performed during
the search process.
Play a round of the game, making the solver guess the secret number 42. Note that you can generate a random-number and make the solver guess it too! We have:
>>>playCurrent bounds: (0,1000) Current bounds: (0,521) Current bounds: (21,521) Current bounds: (31,521) Current bounds: (36,521) Current bounds: (39,521) Current bounds: (40,521) Current bounds: (41,521) Current bounds: (42,521) Solved in: 9 guesses: 1000 0 21 31 36 39 40 41 42
