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