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

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("don optimized algorithm") OR ((("_ optimization algorithm") OR ("_ optimization algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"don optimized algorithm\") or (((\"_ optimization algorithm\") OR (\"_ optimization algorithms\"))))~".
• Removing quotes may allow a broader search: (( don optimized algorithm ) or ((( _ optimization algorithm ) OR ( _ optimization algorithms ))))~.
• Adding a wildcard symbol may retrieve word variants: (("don optimized algorithm") or ((("_ optimization algorithm") OR ("_ optimization algorithms"))))*.
