Perhaps you should try some spelling variations:
"don estimation algorithms" » "don optimization algorithms", "don optimisation algorithm", "don approximation algorithms", "pose estimation algorithms", "_ estimation algorithms", "motion estimation algorithms"
"_ optimize algorithms" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimized algorithm", "_ optimise algorithms"
"jose estimation algorithm" » "pose estimation algorithm", "risk estimation algorithm", "cover estimations algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("don estimation algorithms") or ("_ optimize algorithms"))) or ("jose estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("don estimation algorithms") OR ("_ optimize algorithms"))) OR ("jose estimation algorithm")).
• Removing quotes may allow a broader search: (((( don estimation algorithms ) or ( _ optimize algorithms ))) or ( jose estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("don estimation algorithms") or ("_ optimize algorithms"))) or ("jose estimation algorithm"))*.
