xgi-optimized 0.11.1

What has been done?:

• Metrics computation has been updated
• The implementation of bipartite graphs has been changed
• Cpp implementation of linegraph
• Added the ability to use the package of accelerated functions on hypergraphs

Metrics computation has been updated

The computation of the linegraph vector centrality metric was accelerated by using the с++ instead of python. For comparison, implementations using the networkx.Graph class were retained.

H_enron = xgi.load_xgi_data("plant-pollinator-mpl-034")
H_enron_cleaned = H_enron.cleanup(
    multiedges=False, singletons=False, isolates=False, relabel=True, in_place=False
)
start_time = time.time()

xgi.centrality.line_vector_centrality(H_enron_cleaned)

middle_time = time.time()

xgi_optimized.vector_centrality(H_enron_cleaned, 3)

end_time = time.time()

print(f"Время выполнения python: {(middle_time-start_time):.6f} секунд")
print(f"Время выполнения c++: {(end_time-middle_time):.6f} секунд")

The implementation of bipartite graphs has been changed.

The implementation for working with bipartite graphs was modified: the igraph.Graph class is now used instead of networkx.Graph for converting from a Hypergraph to a bipartite graph and back to a Hypergraph .

hg = xgi.Hypergraph()
hg.add_edges_from(
    [[1, 2, 3], [3, 4, 5,8], [1, 4, 10, 11, 12], [7,0,8], [5,7,2]]
)

bpg = xgi_optimized.biparite_graph.to_bipartite_graph(hg)

Cpp implementation of сhecking graph connectivity

size = 38
hg = xgi.fast_random_hypergraph(size,[0.1, 0.2, 0.02,0.04])
start_time = time.time() 
xgi_optimized.connected.is_connected(hg)
middle_time = time.time()
xgi.centrality.is_connected(hg)
end_time = time.time()
print(f"Время выполнения c++: {(middle_time-start_time):.6f} секунд")
print(f"Время выполнения python: {(end_time-middle_time):.6f} секунд")

middle_time = time.time()
