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

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

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