| Logical rules |
Experimental observation signs are kept. A node signed as “0” must receive only one influence signed as “0” or at least one “” and one “−” in- fluence. A signed node must be jus- tified by at least one signed influence. |
Experimental observation signs are kept. A node is signed “0” ei- ther if it only receives 0- influences or the same pro- portion of signed “ −”, “ ” influences. A node is signed following the majority sign from all its received influences. |
