# Game from A. Trautman.

# Implementing a program that will play the Nintendo DS game of
# loves-me / loves-me-not.

# The game starts with a number of petals to pluck from a flower. To
# make the game more interesting, each player can remove up to 4
# petals from the flower and at least 1. In the end the player wins if
# either the game ends with a "loves me" for him or a "loves me not"
# for the adversary. The first move is a "loves me".

# This is a small example of implementing the MinMax and Alpha-Beta
# algorithms.

from loves_me_not import *
from random import *

# A function that runs the game starting from a given number of
# petals. The first turn is always left to the player and the first
# petal is always "loves me". The function alternates the moves
# between the player and one algorithm - alpha-beta or minmax - until
# there are no petals left to remove.
