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"
"attribute optimisation algorithm" » "attribute optimization algorithm", "attribute optimization algorithms", "attribute estimation algorithm", "attribute estimation algorithms"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"attribute optimisation algorithm\") OR (\"parameters optimisation algorithmssssss\"))~".
• Removing quotes may allow a broader search: (( attribute optimisation algorithm ) OR ( parameters optimisation algorithmssssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("attribute optimisation algorithm") OR ("parameters optimisation algorithmssssss"))*.
