RRT is a searching algorithm applied by building a space filling tree from samples drawn randomly of high-dimensional search spaces . import networkx as nx import numpy as np from sklearn.neighbors import KDTree class RRT: def __init__(self,x_init): self.tree = nx.DiGraph() self.tree.add_node(x_init) def nearest_neighbour(x_rand,rrr): dist=1000 x_rand = np.array(x_rand) for node inContinue Reading
