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

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: (((("dan optimized algorithm") OR ("dan optimizer algorithms"))) or ("jose estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("dan optimized algorithm") OR ("dan optimizer algorithms"))) OR ("jose estimation algorithms")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"dan optimized algorithm\") OR (\"dan optimizer algorithms\"))) or (\"jose estimation algorithms\"))".
• Removing quotes may allow a broader search: (((( dan optimized algorithm ) OR ( dan optimizer algorithms ))) or ( jose estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("dan optimized algorithm") OR ("dan optimizer algorithms"))) or ("jose estimation algorithms"))*.
