# backjumping造句

## 例句與造句

1. Backjumping at internal nodes cannot be done as for leaf nodes.
2. It uses the same rationale of graph-based backjumping.
3. The backjumping algorithm by Gaschnig does a backjump only in leaf dead ends.
4. The efficiency of a backjumping algorithm depends on how high it is able to backjump.
5. In practice, backjumping algorithms use the lowest index they can efficiently prove to be a safe jump.
6. It's difficult to find backjumping in a sentence. 用backjumping造句挺難的
7. Jumpback learning is based on storing as constraints the inconsistent assignments that would be found by conflict-based backjumping.
8. The simplest condition in which backjumping is possible is when all values of a variable have been proved inconsistent without further branching.

14. His most notable contribution is his invention of Conflict-directed backjumping, an advanced technique for reducing search in constraint problems by avoiding unnecessary work on backtracking.
15. When retracting from a leaf node, the set of variables that are in constraint with it is created and " sent back " to its parent, or ancestor in case of backjumping.
16. When further backtracking or backjumping from the node, the variable of the node is removed from this set, and the set is sent to the node that is the destination of backtracking or backjumping.
