Perhaps you should try some spelling variations:
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ optimisation algorithm"
"cost optimizer algorithms" » "cost optimized algorithms", "cost optimization algorithms", "most optimizer algorithms"
"post optimized algorithm" » "post 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: (("_ estimation algorithms") or ((("cost optimizer algorithms") or ("post optimized algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("_ estimation algorithms") OR ((("cost optimizer algorithms") OR ("post optimized algorithm"))))*.
• Removing quotes may allow a broader search: (( _ estimation algorithms ) or ((( cost optimizer algorithms ) or ( post optimized algorithm ))))*.
