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

Try widening your search to All Fields.

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 algorithm") or ("one optimized algorithms"))) or ("sphere estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("d_ optimized algorithm") OR ("one optimized algorithms"))) OR ("sphere estimation algorithm")).
• Removing quotes may allow a broader search: (((( d_ optimized algorithm ) or ( one optimized algorithms ))) or ( sphere estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("d_ optimized algorithm") or ("one optimized algorithms"))) or ("sphere estimation algorithm"))*.
