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

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