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

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 ((("does optimized algorithms") or ("does optimized algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("_ estimation algorithms") OR ((("does optimized algorithms") OR ("does optimized algorithm"))))*.
• Removing quotes may allow a broader search: (( _ estimation algorithms ) or ((( does optimized algorithms ) or ( does optimized algorithm ))))*.
