Perhaps you should try some spelling variations:
"parameter optimisation algorithmssssss" » "parameter optimization algorithms", "parameter optimization algorithmssssss", "parameter estimation algorithmssssss", "parameter optimization algorithmsssssss", "parameter estimation algorithmsssssss"
"attributes optimisation algorithm" » "attribute optimization algorithm", "attributes optimization algorithms", "attributes estimation algorithm", "attributes estimation algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("parameter optimisation algorithmssssss") OR ("attributes optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"parameter optimisation algorithmssssss\") OR (\"attributes optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( parameter optimisation algorithmssssss ) OR ( attributes optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("parameter optimisation algorithmssssss") OR ("attributes optimisation algorithm"))*.
