Perhaps you should try some spelling variations:
"don optimizer algorithms" » "don optimized algorithms", "don optimization algorithms"
"don optimized algorithm" » "don optimized algorithms", "_ optimized algorithm"
"jose estimation algorithm" » "pose estimation algorithm", "risk estimation algorithm", "cover estimations algorithm"

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

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