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

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

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