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