1 Removal of non-applicable rules

The following rules have arguments which are not in normal form. Due to the strategy restrictions these can be removed.

There are no rules.

1.1.1.1 Usable Rules Processor

We restrict the rewrite rules to the following usable rules of the DP problem.

There are no rules.

1.1.1.1.1 Innermost Lhss Removal Processor

We restrict the innermost strategy to the following left hand sides.

There are no lhss.
