MAYBE * Step 1: Failure MAYBE + Considered Problem: - Strict TRS: f(0()) -> true() f(1()) -> false() f(s(x)) -> f(x) g(x,c(y)) -> g(x,g(s(c(y)),y)) g(s(x),s(y)) -> if(f(x),s(x),s(y)) if(false(),x,y) -> y if(true(),x,y) -> x - Signature: {f/1,g/2,if/3} / {0/0,1/0,c/1,false/0,s/1,true/0} - Obligation: innermost runtime complexity wrt. defined symbols {f,g,if} and constructors {0,1,c,false,s,true} + Applied Processor: NaturalPI {shape = Mixed 3, restrict = NoRestrict, uargs = UArgs, urules = URules, selector = Nothing} + Details: Incompatible MAYBE
