[TIMES](X1,X2) = 3.X1.X2 + 3.X1 + 3.X2

Problem 1.2: 

SCC Processor:
-> FAxioms:
 TIMES(times(x3,x4),x5) = TIMES(x3,times(x4,x5))
 TIMES(x3,x4) = TIMES(x4,x3)
-> Pairs:

-> Rules:
 plus(s(x),y) -> s(plus(x,y))
 plus(x,0) -> x
 times(s(x),y) -> plus(times(x,y),y)
 times(x,plus(y,z)) -> plus(times(x,y),times(x,z))
 times(x,0) -> 0
-> SRules:
 TIMES(times(x3,x4),x5) -> TIMES(x3,x4)
 TIMES(x3,times(x4,x5)) -> TIMES(x4,x5)
->Strongly Connected Components:
 There is no strongly connected component

The problem is finite.
