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