YES We show the termination of the TRS R: *(x,+(y,z)) -> +(*(x,y),*(x,z)) -- SCC decomposition. Consider the dependency pair problem (P, R), where P consists of p1: *#(x,+(y,z)) -> *#(x,y) p2: *#(x,+(y,z)) -> *#(x,z) and R consists of: r1: *(x,+(y,z)) -> +(*(x,y),*(x,z)) The estimated dependency graph contains the following SCCs: {p1, p2} -- Reduction pair. Consider the dependency pair problem (P, R), where P consists of p1: *#(x,+(y,z)) -> *#(x,y) p2: *#(x,+(y,z)) -> *#(x,z) and R consists of: r1: *(x,+(y,z)) -> +(*(x,y),*(x,z)) The set of usable rules consists of (no rules) Take the reduction pair: generalized weighted path order (>=MG, >MG) base order 1: max/plus interpretation on natural numbers: *#_A(x1,x2) = x2 +_A(x1,x2) = max{x1, x2} base order 2: precedence: + > *# partial status: pi(*#) = [2] pi(+) = [1, 2] The following rules are removed: p1 -- SCC decomposition.
