Crossing minimaization whilst preventing excess node re location ? [message #1832297]

Hi there,

We are using ELK with Sirius to layout our diagrams.

With the settings below we minimize crossing:

setProperty(LayeredOptions.CROSSING_MINIMIZATION_STRATEGY, CrossingMinimizationStrategy.INTERACTIVE);
topNode.setProperty(LayeredOptions.CROSSING_MINIMIZATION_SEMI_INTERACTIVE, true);

However in certain case this results in crossing because it won't reposition the node. If we use the setting Layer_SWEEP, it results in nodes being re positioned where not necessary.

Is it possible to achieve a middle ground here where it will re position to avoid crossing but keep their position if no crossing would occur ?

Many Thanks
Jonathan

This might be a little late, however, you can try to use the considerModelOrder options.
This tries to use the order of the model (here a textual one) to do crossing minimization. If the order is indeed crossing minimal it will be taken. If it is not a better solution might be taken. For details please look here.

With the next ELK release (0.8.0 probably) it should also be possible to do cycle breaking by model order.
