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

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