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