Returns the current number of epochs and execution status, as a string.

initialize

public void initialize()

Description copied from class: AbstractLayout

Initializer, calls intialize_local and initializeLocations to start construction process.

Specified by:

initialize in interface Layout<V,E>

Specified by:

initialize in class AbstractLayout<V,E>

step

public void step()

Advances the current positions of the graph elements.

Specified by:
