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