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