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

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