1.1.2.1.1 Reduction Pair Processor with Usable Rules

Using the argument filter

π(5^#)	=	1
π(1^#)	=	1

in combination with the following Weighted Path Order with the following precedence and status

prec(0^#)	=	0	status(0^#)	=	[]	list-extension(0^#)	=	Lex
prec(1)	=	1	status(1)	=	[1]	list-extension(1)	=	Lex
prec(4)	=	0	status(4)	=	[]	list-extension(4)	=	Lex
prec(5)	=	0	status(5)	=	[1]	list-extension(5)	=	Lex
prec(3)	=	0	status(3)	=	[]	list-extension(3)	=	Lex
prec(0)	=	2	status(0)	=	[1]	list-extension(0)	=	Lex
prec(2)	=	0	status(2)	=	[1]	list-extension(2)	=	Lex

and the following Max-polynomial interpretation

[0^#(x₁)]	=	0
[1(x₁)]	=	x₁ + 0
[4(x₁)]	=	0
[5(x₁)]	=	x₁ + 0
[3(x₁)]	=	0
[0(x₁)]	=	x₁ + 0
