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

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