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