Python Node.traverseInOrder Examples

Example #1

File: program.py Project: chetan51/genesys

  def mate(self, program):
    childA = Node.copy(self.root)
    childB = Node.copy(program.root)

    nodeA = random.choice(Node.traverseInOrder(childA))
    nodeB = random.choice(Node.traverseInOrder(childB))

    childA = Node.replace(childA, nodeA, nodeB)
    childB = Node.replace(childB, nodeB, nodeA)

    return [Program(childA), Program(childB)]

Example #2

File: program.py Project: jaags/genesys

    def mate(self, program):
        childA = Node.copy(self.root)
        childB = Node.copy(program.root)

        nodeA = random.choice(Node.traverseInOrder(childA))
        nodeB = random.choice(Node.traverseInOrder(childB))

        childA = Node.replace(childA, nodeA, nodeB)
        childB = Node.replace(childB, nodeB, nodeA)

        return [Program(childA), Program(childB)]

         else:
