How to use ?

Import the package modules:

from dhd import city, connect, evolve, load

Load the geometries of the city of Vevey in Switzerland:

vevey = city.City('Vevey, Switzerland', sources=Point(333795, 5147530))
streets = vevey.get_streets()
sinks = vevey.select_sinks(min_load=300)
sources = vevey.get_sources()

Connect the selected buildings (sinks) and the source to the streets network:

vertices, terminals = connect.connect_terminals(streets, sinks, sources)

Run the evolutive algorithm to seek the best possible heating network within five generations:

N = 5
evolution = evolve.run_evolution(vertices, terminals, N)
tst = evolve.get_best_terminal_steiner_tree(vertices, terminals, evolution)

Spread the buildings load over the district heating pipelines:

pipelines = load.load_the_pipelines(tst, terminals)
