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