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

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