No "->="-rules.

Decomposed conditions and removed infeasible rules if possible.

Optimized the infeasibility problem if possible.

This is ultra-RL and deterministic.

This is not operationally terminating and confluent.

Failed to prove infeasibility of the linearized conditions by means of narrowing trees.

This is not ultra-RL and deterministic.
