System.OutOfMemoryException thrown when calling LayeredLayout.Arrange() on a diagram with 135 nodes (Read 3577 times)

	I two versions of a diagram. The earlier version has 94 nodes and LayeredLayout.Arrange() finishes in about 4 minutes. The later version has 135 nodes and causes this exception to be thrown when LayeredLayout.Arrange() is called: System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown. Is there anything I can do get LayeredLayout.Arrange() to finish faster and not throw exceptions?

	It will work much faster if you set the layout's StartNode and EndNode properties, or enable EnforceLinkFlow. Otherwise the algorithm tries to find the longest path in the graph and build layers along it, and that might be time and memory consuming in large graphs. Even if running path-finding, you can still limit how much time LayeredLayout will look for long paths by setting the TimeLimit property. That should indirectly limit how much memory is required too. I hope that helps, Stoyan

	Do you know what release added the StartNode, EndNode, and EnforceLinkFlow properties. We are using 5.0.1.29913 and I don't see any of them in the LayeredLayout class.

	We upgraded to 6.0.3 and it resolved all of the issues we were seeing with long layout times. Thanks.
