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