Perhaps you should try some spelling variations:
"cover estimation algorithms" » "cover estimation algorithm", "cover optimization algorithms", "cover optimisation algorithm", "cover estimations algorithms", "pose estimation algorithms", "sphere estimation algorithms"
"d_ optimized algorithms" » "d_ optimizer algorithms", "d_ optimization algorithms", "d_ optimizer algorithmss", "_ optimized algorithms", "_ optimize algorithms", "_ optimise algorithms"
"one optimized algorithm" » "one optimizer algorithms", "_ optimized algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("d_ optimized algorithms") OR ("one optimized algorithm"))) OR ("cover estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"d_ optimized algorithms\") OR (\"one optimized algorithm\"))) OR (\"cover estimation algorithms\"))".
• Removing quotes may allow a broader search: (((( d_ optimized algorithms ) OR ( one optimized algorithm ))) OR ( cover estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("d_ optimized algorithms") OR ("one optimized algorithm"))) OR ("cover estimation algorithms"))*.
