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