Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ optimisation algorithm", "_ optimized algorithms", "_ optimizer algorithms"
"_ estimation algorithms" » "_ optimisation algorithm", "_ approximation algorithms"
"jose estimation algorithm" » "pose estimation algorithm", "risk estimation algorithm", "cover estimations 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 algorithms") or ("_ estimation algorithms"))) or ("jose estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ optimization algorithms") OR ("_ estimation algorithms"))) OR ("jose estimation algorithm")).
• Removing quotes may allow a broader search: (((( _ optimization algorithms ) or ( _ estimation algorithms ))) or ( jose estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("_ optimization algorithms") or ("_ estimation algorithms"))) or ("jose estimation algorithm"))*.
