backtrack

Section 5 introduces conflict sets and our generic tìm kiếm algorithm, and recasts backtracking tìm kiếm in that framework.

The presence of the all/2 collector avoids the need for backtracking over multiple remote answers.

Chapter 6 improves naive backtracking using look-back schemes for backjumping and learning.

Unfortunately, the presence of non-deterministic strategies and rules limits its applicability, because backtracking requires access to tướng structures that would otherwise be reused.

The failed attempt to tướng establish this goal in the existing plan network supports expansion, failure, or backtracking as an option.

However, the system will add new preconditions rather than thở backtracking if an unsafe state is generated during synthesis.

Still, using the trail for storing both references which have to tướng be reset upon backtracking and inter-block references has important disadvantages.

Profiling revealed that in this benchmark, upon backtracking and untrailing it is often needed to tướng remove several cells at once from a certain remembered phối.

14 again because backtracking does not remove the reason for the failure !.

By contrast, backtracking automata cannot be easily analyzed.

The other kind of error - incompleteness via infinite loops or backtracking failure - continues to tướng be bothersome, of course: dependent types tự not save us there.

Upon backtracking the registers that held these system variables are restored from the choicepoint.

If a sub-string matches the contextual restrictions, the corresponding operation applies without later backtracking.

Any feature structures and definite clause programs can be used to tướng express the constraint, which may include backtracking, cut, negation-as-failure, assertion and any other operations.

In this case backtracking must take place to tướng the most recent choice point either in clause selection or in unification.
