Perhaps you should try some spelling variations:
"parameters optimisation algorithmssssss" » "parameters optimization algorithms", "parameter optimization algorithmssssss", "parameter estimation algorithmssssss", "parameters optimization algorithmsssssss", "parameters estimation algorithmssssss", "parameters 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: (("attributes optimisation algorithm") OR ("parameters optimisation algorithmssssss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"attributes optimisation algorithm\") OR (\"parameters optimisation algorithmssssss\"))".
• Removing quotes may allow a broader search: (( attributes optimisation algorithm ) OR ( parameters optimisation algorithmssssss )).
• Adding a wildcard symbol may retrieve word variants: (("attributes optimisation algorithm") OR ("parameters optimisation algorithmssssss"))*.
