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