PropagationRule
​
PropagationRule
[a,{
b
1
,…,
b
n
},f]
returns a rewrite rule propagating a unary process with input
a
through an
n
-ary node with outputs
b
1
,â-¦,
b
n
, applying
f
to the node's label.
​
Details and Options
▪
Encodes the interaction-net commutation law: the process is duplicated onto each branch of the node, and the node's label is transformed by
f
as it passes through.
▪
The following options can be given:
Option
Default
Description
"Polarized"
True
show port direction arrows
"Floating"
True
allow node ports to match in any order
