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

You may be able to get more results by adjusting your search query.

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