Enter ``1'' at #19.2 to choose a default layout appropriate for ``learning'' (described in #27). A prompt to set the node display (similar to the following) is presented (see also #20.2):
nodes: none-n 2d-B 1d-b hex-h, dec-c, spot-s (default-B):
(``dec-c'' if n<=32, ``2d-bits-b`` for a 2d network )
The attractor basin nodes can be displayed in a variety of different ways,
``s'' - as small circles or spots.
``c'' - in decimal (for the network size, n<=32).
``h'' - in hex
``b'' - as bits in a 1d or 2d graphic array, drawing with mouse.
``B'' - (for 1 networks only) as bits shown in 2d .
If ``b'' is selected, the bit pattern will be displayed in 1d or 2d depending on the dimensions of the network. If ``B'' is selected the 1d network is represented in 2d as a square or rectangular bit pattern, ij. The default i (the number of columns) is set automatically as the highest factor of the network size n, but the i j setting may be changed as described in the ``seed`` prompt #15.7.2.
Selecting the default layout for learning is a short cut, further layout and presentation options will be skipped. The full range of node display options may be set at #20.2).
