升壓三角洲步進

Question

我想使用並行升壓圖庫運行Delta Stepping算法，但它不能編譯。能否請你幫忙。

Answer 1

你似乎混淆了位置的人命名參數。

的距離和權重貼圖需要傳遞，而不是包裝成這個過載位置參數對象：

template<typename Graph, typename PredecessorMap, typename DistanceMap, 
     typename EdgeWeightMap> 
void 
delta_stepping_shortest_paths 
    (const Graph& g, 
    typename graph_traits<Graph>::vertex_descriptor s, 
    PredecessorMap predecessor, DistanceMap distance, EdgeWeightMap weight) 
{ 

因此，刪除指定的參數的構造函數：

graph::distributed::delta_stepping_shortest_paths(g, start, dummy_property_map(), 
     distance_map(get(vertex_distance, g)), 
     weight_map(get(edge_weight, g))); 

應

graph::distributed::delta_stepping_shortest_paths(g, start, dummy_property_map(), 
     get(vertex_distance, g), 
     get(edge_weight, g));
