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