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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("parameters optimisation algorithmssssss") or ("attribute optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("parameters optimisation algorithmssssss") OR ("attribute optimisation algorithm")).
• Removing quotes may allow a broader search: (( parameters optimisation algorithmssssss ) or ( attribute optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("parameters optimisation algorithmssssss") or ("attribute optimisation algorithm"))*.
