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

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: "((((\"_ optimized algorithms\") OR (\"_ optimize algorithms\"))) OR (\"sphere estimation algorithm\"))~".
• Removing quotes may allow a broader search: (((( _ optimized algorithms ) OR ( _ optimize algorithms ))) OR ( sphere estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimized algorithms") OR ("_ optimize algorithms"))) OR ("sphere estimation algorithm"))*.
