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