Perhaps you should try some spelling variations:
"mot estimation algorithms" » "mot optimization algorithms", "mot optimisation algorithm", "mot approximation algorithms", "motion estimation algorithms", "pose estimation algorithms"
"_ estimation algorithms" » "_ optimization algorithms", "_ optimisation algorithm", "_ approximation 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: (((("mot estimation algorithms") OR ("_ estimation algorithms"))) or ("jose estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("mot estimation algorithms") OR ("_ estimation algorithms"))) OR ("jose estimation algorithm")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"mot estimation algorithms\") OR (\"_ estimation algorithms\"))) or (\"jose estimation algorithm\"))".
• Removing quotes may allow a broader search: (((( mot estimation algorithms ) OR ( _ estimation algorithms ))) or ( jose estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("mot estimation algorithms") OR ("_ estimation algorithms"))) or ("jose estimation algorithm"))*.
