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

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: (((("cover estimations algorithms") OR ("_ estimation algorithms"))) OR ("_ optimized algorithm"))~.
• Removing quotes may allow a broader search: (((( cover estimations algorithms ) or ( _ estimation algorithms ))) or ( _ optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cover estimations algorithms") or ("_ estimation algorithms"))) or ("_ optimized algorithm"))*.
