Perhaps you should try some spelling variations:
"jose estimation algorithms" » "jose estimation algorithm", "jose optimization algorithms", "jose optimisation algorithm", "pose estimation algorithms", "cover estimations algorithms", "pulses estimation algorithms"
"risk estimation algorithms" » "risk estimation algorithm", "risk optimization algorithms", "risk optimisation algorithm", "pose estimation algorithms"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer 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: (("_ optimized algorithm") or ((("jose estimation algorithms") OR ("risk estimation algorithms"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("_ optimized algorithm") OR ((("jose estimation algorithms") OR ("risk estimation algorithms")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ optimized algorithm\") or (((\"jose estimation algorithms\") OR (\"risk estimation algorithms\"))))".
• Removing quotes may allow a broader search: (( _ optimized algorithm ) or ((( jose estimation algorithms ) OR ( risk estimation algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("_ optimized algorithm") or ((("jose estimation algorithms") OR ("risk estimation algorithms"))))*.
