768 +{{id name="addUnnecessaryBendpoints"/}}Add Unnecessary BendpointsBy default, KLay Layered tries not to add bendpoints to an edge at positions where the edge doesn't change direction since there's no real bend there. Turning this option on forces such bend points. More specifically, a bend point is added for each edge that spans more than one layer at the point where it crosses a layer. If hierarchy layout is turned on, a bend point is also added whenever the edge crosses a hierarchy boundary.

782 +* {{code language="none"}}LAYER_SWEEP{{/code}}
709 709  The layer sweep algorithm iterates multiple times over the layers, trying to find node orderings that minimize the number of crossings. The algorithm uses randomization to increase the odds of finding a good result. To improve its results, consider increasing the //Thoroughness// option, which influences the number of iterations done. The //Randomization// seed also influences results.
710 -* INTERACTIVE
784 +* {{code language="none"}}INTERACTIVE{{/code}}
711 711  Orders the nodes of each layer by comparing their positions before the layout algorithm was started. The idea is that the relative order of nodes as it was before layout was applied is not changed. This of course requires valid positions for all nodes to have been set on the input graph before calling the layout algorithm. The interactive layer sweep algorithm uses the //Interactive Reference Point// option to determine which reference point of nodes are used to compare positions.

844 -* NETWORK_SIMPLEX
888 +* {{code language="none"}}NETWORK_SIMPLEX{{/code}}
845 845  This algorithm tries to minimize the length of edges. This is the most computationally intensive algorithm. The number of iterations after which it aborts if it hasn't found a result yet can be set with the [[Maximal Iterations>>doc:||anchor="maximalInterations"]] option.
846 -* LONGEST_PATH
890 +* {{code language="none"}}LONGEST_PATH{{/code}}
847 847  A very simple algorithm that distributes nodes along their longest path to a sink node.
848 -* INTERACTIVE
892 +* {{code language="none"}}INTERACTIVE{{/code}}
849 849  Distributes the nodes into layers by comparing their positions before the layout algorithm was started. The idea is that the relative horizontal order of nodes as it was before layout was applied is not changed. This of course requires valid positions for all nodes to have been set on the input graph before calling the layout algorithm. The interactive node layering algorithm uses the //Interactive Reference Point// option to determine which reference point of nodes are used to compare positions.

862 862  Computes a balanced placement.

865 -* SIMPLE
903 +* {{code language="none"}}INTERACTIVE{{/code}}
904 +Tries to keep the preset y coordinates of nodes from the original layout. For dummy nodes, a guess is made to infer their coordinates. Requires the other interactive phase implementations to have run as well.

874 -Since ports have a size, we need a concrete point inside the port that edges should start or end in. In KLay Layered, this is referred to as the //port anchor//. By default, the center of each port is used as its port anchor, but this behavior can be overridden by setting an explicit port anchor.
875 -
876 -In the following example, the port anchor of the left port was moved upwards, while the port anchor of the second port was moved downwards:

886 -There are heuristics in use all over KLay Layered whose results often improve with the number of iterations computed. The thoroughness is a measure for telling KLay Layered to compute more iterations to improve the quality of results, at the expense of performance.
