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

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: (((("done optimized algorithm") OR ("dung optimized algorithm"))) OR ("_ optimization algorithm"))~.
• Removing quotes may allow a broader search: (((( done optimized algorithm ) or ( dung optimized algorithm ))) or ( _ optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("done optimized algorithm") or ("dung optimized algorithm"))) or ("_ optimization algorithm"))*.
