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