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

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