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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("cost optimizer algorithms") or ((("_ estimation algorithms") or ("_ optimized algorithms"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("cost optimizer algorithms") OR ((("_ estimation algorithms") OR ("_ optimized algorithms")))).
• Removing quotes may allow a broader search: (( cost optimizer algorithms ) or ((( _ estimation algorithms ) or ( _ optimized algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("cost optimizer algorithms") or ((("_ estimation algorithms") or ("_ optimized algorithms"))))*.
