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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("_ optimization algorithm") or ("_ optimize algorithms"))) or ("sphere estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ optimization algorithm") OR ("_ optimize algorithms"))) OR ("sphere estimation algorithm"))*.
• Removing quotes may allow a broader search: (((( _ optimization algorithm ) or ( _ optimize algorithms ))) or ( sphere estimation algorithm ))*.
