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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"_ optimization algorithm\") OR (\"_ optimized algorithm\"))) OR (\"cover estimation algorithms\"))~".
• Removing quotes may allow a broader search: (((( _ optimization algorithm ) OR ( _ optimized algorithm ))) OR ( cover estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimization algorithm") OR ("_ optimized algorithm"))) OR ("cover estimation algorithms"))*.
