Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ estimation algorithms", "_ estimation algorithm", "_ optimized algorithms"
"_ 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 algorithms"))) OR ("_ optimisation algorithm"))~.
• Removing quotes may allow a broader search: (((( don optimized algorithm ) or ( _ optimization algorithms ))) or ( _ optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("don optimized algorithm") or ("_ optimization algorithms"))) or ("_ optimisation algorithm"))*.
