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