Perhaps you should try some spelling variations:
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ optimisation algorithm"
"poses optimized algorithms" » "poses optimizer algorithms", "poses optimization algorithms", "poses optimizer algorithmss", "posts optimized algorithms", "joses optimized algorithms", "doses optimized algorithms"
"pose optimized algorithm" » "pose optimizer algorithms", "post optimized algorithm", "jose optimized algorithm", "dose optimized 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: (((("pose optimized algorithm") or ("poses optimized algorithms"))) or ("_ estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("pose optimized algorithm") OR ("poses optimized algorithms"))) OR ("_ estimation algorithms")).
• Removing quotes may allow a broader search: (((( pose optimized algorithm ) or ( poses optimized algorithms ))) or ( _ estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("pose optimized algorithm") or ("poses optimized algorithms"))) or ("_ estimation algorithms"))*.
