This packages is based and inspired in aima-python: https://code.google.com/p/aima-python/
We implement most of the searches in aima-python plus some extra options. Besides, we make some improvements in terms of code readability, installation, testing, and others.
Just get it:
pip install simpleai
Simple AI allows you to define problems and look for the solution with different strategies. Another samples are in the samples directory, but here is an easy one.
This problem tries to create the string "HELLO WORLD" using the A* algorithm:
from simpleai.models import Problem from simpleai.search import astar GOAL = 'HELLO WORLD' class HelloProblem(Problem): def actions(self, state): if len(state) < len(GOAL): return [c for c in ' ABCDEFGHIJKLMNOPQRSTUVWXYZ'] else: return  def result(self, state, action): return state + action def is_goal(self, state): return state == GOAL def heuristic(self, state): # how far are we from the goal? wrong = sum([1 if state[i] != GOAL[i] else 0 for i in range(len(state))]) missing = len(GOAL) - len(state) return wrong + missing problem = HelloProblem(initial_state='') result = astar(problem) print result.state print result.path()
