Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm", "_ estimation algorithms"
"cost optimized algorithm" » "cost optimized algorithms", "cost optimizer algorithms"
"most optimized algorithm" » "most optimized algorithms", "most optimizer algorithms"

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