621	621	This section explains every layout option in more detail. See [[the KIML documentation>>doc:KIML Layout Options]] for more information on KIML layout options. Those options are only mentioned here if KLay Layered adds some custom behavior.

	623	+== Crossing Minimization ==
	624	+
	625	+Crossing minimization determines the ordering of nodes in each layer, which influences the number of edge crossings. This option switches between one of several algorithms that can be used to minimize crossings. Possible values are:
	626	+
	627	+* LAYER_SWEEP
	628	+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.
	629	+* INTERACTIVE
	630	+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.
	631	+
	632	+== Interactive Reference Point ==
	633	+
	634	+Interactive layering and crossing minimization algorithms use node positions to sort nodes into layers or to determine the order of nodes in each layer. However, it is unclear if for example the top left corners of nodes should be compared, or the bottom left corners — different settings might lead to different results. The interactive reference point determines which part of nodes is used to compare their positions. It provides the following settings:
	635	+
	636	+* TOP_LEFT
	637	+The top left corner of a node is taken as the reference point.
	638	+* CENTER
	639	+The center of a node is taken as the reference point.
	640	+
	641	+== Thoroughness ==
	642	+
	643	+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.
