Research Question: How can we verify the termination and error-freedom of logic programs with block declarations?

Methodology: The researchers presented two approaches to verify the termination and error-freedom of logic programs with block declarations. The first approach aimed to eliminate the problem of speculative output bindings. The second approach was based on identifying predicates that do not require the textual position of an atom using that predicate to be relevant for termination. They considered three distinctive features: allowing predicates to run in multiple modes, using block declarations as a simple and efficient delay construct, and taking the selection rule into account.

Results: The researchers developed methods for verifying programs with delay declarations. They considered two aspects of verication: ensuring termination and preventing type or instantiation errors related to the use of built-ins. Their methods can be used to verify existing programs and assist in writing new ones.

Implications: The researchers' work has several implications. First, it shows that block declarations, which are a simple and efficient delay construct, are sufficient to ensure the desired properties. Second, it takes the selection rule into account, which is important for verifying programs with delay declarations. Lastly, it allows for predicates to run in multiple modes, which is an application of delay declarations.
