Pboolnet | SuperCollider 3.13.0 Help

Description

Boolean network pattern after: http://farben.latrobe.edu.au/mikropol/volume6/dorin_a/dorin_a.html

Part of MathLib, a diverse library of mathematical functions.

Class Methods

.new

Arguments:

nodes	A list of pairs of initial states (0 or 1) and binary boolean operation selectors (e.g., `\and`, `\or`, `\xor`).
repeats	Number of times to repeat the pattern.
loops	Number of times to loop a particular network configuration.

Examples

Print out the stream to demonstrate what it looks like

same as above, but with a loop
