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

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: (("attributes optimization algorithms") or ("parameters optimization algorithmssssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("attributes optimization algorithms") OR ("parameters optimization algorithmssssss")).
• Removing quotes may allow a broader search: (( attributes optimization algorithms ) or ( parameters optimization algorithmssssss )).
• Adding a wildcard symbol may retrieve word variants: (("attributes optimization algorithms") or ("parameters optimization algorithmssssss"))*.
