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