Perhaps you should try some spelling variations:
"_ optimization algorithm" » "_ optimization algorithms", "_ optimisation algorithm", "_ estimation algorithm"
"don optimizer algorithms" » "don optimized algorithms", "don optimization algorithms"
"done optimized algorithm" » "done optimized algorithms", "dong optimized algorithm", "one 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: (((("done optimized algorithm") or ("don optimizer algorithms"))) or ("_ optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("done optimized algorithm") OR ("don optimizer algorithms"))) OR ("_ optimization algorithm")).
• Removing quotes may allow a broader search: (((( done optimized algorithm ) or ( don optimizer algorithms ))) or ( _ optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("done optimized algorithm") or ("don optimizer algorithms"))) or ("_ optimization algorithm"))*.
