كود الخوارزمية (Info)


ما يلي هو تطبيق الخوارزمية بلغة java, وهذا التطبيق هو ليس الأفضل بالضرورة ولكنه نموذج لطريقة التطبيق :

class Dijkstra { double[] dist = new double[G.V()]; Edge[] pred = new Edge[G.V()]; public Dijkstra(WeightedDigraph G, int s) { boolean[] marked = new boolean[G.V()]; for (int v = 0; v <G.V(); v++) dist[v] = Double.POSITIVE_INFINITY; MinPQplus<Double, Integer> pq; pq = new MinPQplus<Double, Integer>(); \Priority Queue dist[s] = 0.0; pq.put(dist[s], s); while (!pq.isEmpty()) { int v = pq.delMin(); if (marked[v]) continue; marked(v) = true; for (Edge e : G.adj(v)) { int w = e.to(); if (dist[w]> dist[v] + e.weight()) { dist[w] = dist[v] + e.weight(); pred[w] = e; pq.insert(dist[w], w); } } } } }
