The beam search is a generalized breadth-first search in which only the "best" *w* neighbors of the current node are enqueued, where *w* is the beam width and "best" is an application-specific heuristic. In general, a beam search with a small beam width might not visit each node in the graph. .. note:: With the default value of ``width=None`` or `width` greater than the maximum degree of the graph, this function equates to a slower version of `~networkx.algorithms.traversal.breadth_first_search.bfs_edges`. All nodes will be visited, though the order of the reported edges may vary. In such cases, `value` has no effect - consider using `bfs_edges` directly instead. Parameters ---------- G : NetworkX graph source : node Starting node for the breadth-first search; this function iterates over only those edges in the component reachable from this node. value : function A function that takes a node of the graph as input and returns a real number indicating how "good" it is. A higher value means it is more likely to be visited sooner during the search. When visiting a new node, only the `width` neighbors with the highest `value` are enqueued (in decreasing order of `value`). width : int (default = None) The beam width for the search. This is the number of neighbors (ordered by `value`) to enqueue when visiting each new node. Yields ------ edge Edges in the beam search starting from `source`, given as a pair of nodes. Examples -------- To give nodes with, for example, a higher centrality precedence during the search, set the `value` function to return the centrality value of the node: >>> G = nx.karate_club_graph() >>> centrality = nx.eigenvector_centrality(G) >>> list(nx.bfs_beam_edges(G, source=0, value=centrality.get, width=3)) [(0, 2), (0, 1), (0, 8), (2, 32), (1, 13), (8, 33)] NcP>[[TRU5TSS9ST5$)zReturns a list of the best neighbors of a node. `v` is a node in the graph `G`. The "best" neighbors are chosen according to the `value` function (higher is better). Only the `width` best neighbors of `v` are returned.
