Perhaps you should try some spelling variations:
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ optimisation algorithm"
"cover estimations algorithm" » "cover estimation algorithm", "cover optimisation algorithm", "pose estimation 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: (((("_ optimized algorithm") OR ("_ estimation algorithms"))) OR ("cover estimations algorithm"))~.
• Removing quotes may allow a broader search: (((( _ optimized algorithm ) or ( _ estimation algorithms ))) or ( cover estimations algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimized algorithm") or ("_ estimation algorithms"))) or ("cover estimations algorithm"))*.
