Perhaps you should try some spelling variations:
"parameters optimization algorithm" » "parameter optimization algorithm", "parameter estimation algorithm", "parameters optimization algorithms", "parameters optimisation algorithm", "parameters estimation algorithm"
"attributed optimization algorithmssssssssss" » "attribute optimization algorithmssssssssss", "attributed optimization algorithmsssssssssss", "attributed optimisation algorithmssssssssss", "attributed estimation algorithmssssssssss"

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 algorithmssssssssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("parameters optimization algorithm") OR ("attributed optimization algorithmssssssssss")).
• Removing quotes may allow a broader search: (( parameters optimization algorithm ) or ( attributed optimization algorithmssssssssss )).
• Adding a wildcard symbol may retrieve word variants: (("parameters optimization algorithm") or ("attributed optimization algorithmssssssssss"))*.
