Perhaps you should try some spelling variations:
"attributed optimization algorithmssssss" » "attributed optimisation algorithm", "attributed optimisation algorithmsssss", "attributed estimation algorithmssssss", "attributed estimation algorithmsssss", "attribute optimization algorithmssssss"
"parameters optimization algorithms" » "parameter optimization algorithms", "parameter estimation algorithms", "parameters optimisation algorithm", "parameters estimation algorithms", "parameters estimation 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: (("parameters optimization algorithms") or ("attributed optimization algorithmssssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("parameters optimization algorithms") OR ("attributed optimization algorithmssssss")).
• Removing quotes may allow a broader search: (( parameters optimization algorithms ) or ( attributed optimization algorithmssssss )).
• Adding a wildcard symbol may retrieve word variants: (("parameters optimization algorithms") or ("attributed optimization algorithmssssss"))*.
