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