solutions.node¶

`Function`	Function object.
`Node`	Node object.
`calc_node_depth`	Calculate the depth of nodes which is following under the target node.
`children_checker`
`copy_node`	Copy function :param node: node object, target node to copy.
`copy_nodes_along_graph`	Copy node object from `root` to the target node based on ``graph’’ This method differs from deepcopy(root) in that it copies only the nodes along ``graph’‘.:param graph: list of ``(i, Node object)’’ where ``i’’ is the index of the next node of graph and ``Node object’’ is the parent node.This graph is obtained by using ``get_parent_node’‘.:return: the index of target node node in the parent, copied the target node object and copied root object..
`func_id_checker`
`get_all_node`	function for getting all node in the solution
`get_all_nonterminal_nodes`	function for getting all terminal node in the solution
`get_all_terminal_nodes`	function for getting all terminal node in the solution
`get_all_terminal_points`	function for getting all terminal points in the solution this function is for crossover in MLPS-GP
`get_graph_to_target`	function for searching a graph from root node to a target node.
`get_n_children`	Get the number of children of function that id = func_id.
`get_parent_node`	function for searching parent node of target node.
`n_children_checker`
`node_array_equal`
`node_checker`
`node_equal`	Function for comparing two nodes.
`nodes_checker`
`set_children`	Setter for children to node :param node: node object.
`set_id`	Function for setting id to node object.
