Perhaps you should try some spelling variations:
"_ approximation algorithm" » "_ approximation algorithms"
"pose optimized algorithm" » "pose optimized algorithms", "pose optimizer algorithms", "poses optimized algorithm", "post optimized algorithm", "jose optimized algorithm"
"most optimized algorithm" » "most optimized algorithms", "most optimizer algorithms"

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 ("most optimized algorithm"))) or ("_ approximation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("pose optimized algorithm") OR ("most optimized algorithm"))) OR ("_ approximation algorithm")).
• Removing quotes may allow a broader search: (((( pose optimized algorithm ) or ( most optimized algorithm ))) or ( _ approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("pose optimized algorithm") or ("most optimized algorithm"))) or ("_ approximation algorithm"))*.
