Explanation of how the node placement algorithms work

[chanpod]

Per the docs, we can select multiple node placement strategies. Is there any documentation on how each of these works? (In detail. What mathematical concepts are they using, etc). Thanks!

For reference, referrring to these
SIMPLE
INTERACTIVE
LINEAR_SEGMENTS
BRANDES_KOEPF
NETWORK_SIMPLEX

No, but I may make a blogpost about these.

SIMPLE: Centers all nodes in a layer such that each layer is as small as possible.
INTERACTIVE: The documentation can only be found in the Javadoc of that class.
The Javadocs of the other strategies mention the paper they are based on.
