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