C# (CSharp) DeepFirstAlgorithm Examples

Example #1

        public void TomWellingToGeorgeLucasDegree2Deep()
        {
            var sourcePerson = new SearchPerson(firstName: "Tom", lastName: "Welling", birthYear: 1977);
            var targetPerson = new SearchPerson(firstName: "George", lastName: "Lucas", birthYear: 1944);

            var sourceNode = _graph.GetDistanceNode(PersonNode.BuildNodeName(sourcePerson));
            var targetNode = _graph.GetDistanceNode(PersonNode.BuildNodeName(targetPerson));

            var calculator = new DeepFirstAlgorithm(_graph);

            var shortestGraph = calculator.GetShortestGraph(sourceNode.Name, targetNode.Name);

            var shortestGraphTargetNode = shortestGraph.GetDistanceNode(PersonNode.BuildNodeName(targetPerson));

            var movieDistance = ForwardUnitTestSample.GetRealMovieDistance(shortestGraphTargetNode);

            Assert.AreEqual(2, movieDistance);

            var stepsList = GraphHelper.GetPaths(shortestGraphTargetNode).ToList();

            Assert.AreEqual(1, stepsList.Count);

            ForwardUnitTestSample.CheckSteps(sourceNode, targetNode, stepsList, movieDistance * 2);
        }
