For all symbols f in {cons_2} we have mu(f) = {1}. The symbols in {U_1} are not replacing on any position. The ordinary context-sensitive dependency pairs DP_o are: SEL(s(N), cons(X, XS)) -> SEL(N, XS) MINUS(s(X), s(Y)) -> MINUS(X, Y) QUOT(s(X), s(Y)) -> QUOT(minus(X, Y), s(Y)) QUOT(s(X), s(Y)) -> MINUS(X, Y) ZWQUOT(cons(X, XS), cons(Y, YS)) -> QUOT(X, Y) The collapsing dependency pairs are DP_c: SEL(s(N), cons(X, XS)) -> XS The hidden terms of R are: from(s(x0)) zWquot(x0, x1) Every hiding context is built from: aprove.DPFramework.CSDPProblem.QCSDPProblem$1@165e0ef2 aprove.DPFramework.CSDPProblem.QCSDPProblem$1@535c825d aprove.DPFramework.CSDPProblem.QCSDPProblem$1@7c7977c1 Hence, the new unhiding pairs DP_u are : SEL(s(N), cons(X, XS)) -> U(XS)
