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

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

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