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