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

Try widening your search to All Fields.

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

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