Perhaps you should try some spelling variations:
"cover estimations algorithms" » "cover estimation algorithms", "cover estimation algorithm", "cover optimization algorithms", "pose estimation algorithms"
"_ optimizer algorithmss" » "_ optimizer algorithms", "_ optimized algorithms", "_ optimize algorithmss", "_ optimise algorithmss"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"

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