Termination of the given IRSwT could be proven:

(0) IRSwT
(1) IRSFormatTransformerProof [EQUIVALENT, 0 ms]
(2) IRSwT
(3) IRSwTTerminationDigraphProof [EQUIVALENT, 85 ms]
(4) TRUE


----------------------------------------

(0)
Obligation:
Rules:
l0(__const_5HAT0, xHAT0, yHAT0) -> l1(__const_5HATpost, xHATpost, yHATpost) :|: __const_5HAT0 = __const_5HATpost && yHATpost <= 0 && yHATpost = xHATpost && xHATpost = __const_5HAT0
l2(x, x1, x2) -> l0(x3, x4, x5) :|: x2 = x5 && x1 = x4 && x = x3
Start term: l2(__const_5HAT0, xHAT0, yHAT0)

----------------------------------------

(1) IRSFormatTransformerProof (EQUIVALENT)
Reformatted IRS to match normalized format (transformed away non-linear left-hand sides, !=, / and %).
----------------------------------------

(2)
Obligation:
Rules:
l0(__const_5HAT0, xHAT0, yHAT0) -> l1(__const_5HATpost, xHATpost, yHATpost) :|: __const_5HAT0 = __const_5HATpost && yHATpost <= 0 && yHATpost = xHATpost && xHATpost = __const_5HAT0
l2(x, x1, x2) -> l0(x3, x4, x5) :|: x2 = x5 && x1 = x4 && x = x3
Start term: l2(__const_5HAT0, xHAT0, yHAT0)

----------------------------------------

(3) IRSwTTerminationDigraphProof (EQUIVALENT)
Constructed termination digraph!
Nodes:
(1) l0(__const_5HAT0, xHAT0, yHAT0) -> l1(__const_5HATpost, xHATpost, yHATpost) :|: __const_5HAT0 = __const_5HATpost && yHATpost <= 0 && yHATpost = xHATpost && xHATpost = __const_5HAT0
(2) l2(x, x1, x2) -> l0(x3, x4, x5) :|: x2 = x5 && x1 = x4 && x = x3

Arcs:
(2) -> (1)

This digraph is fully evaluated!

(4)
TRUE
