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

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

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