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