Perhaps you should try some spelling variations:
"same optimization algorithmss" » "same optimization algorithms", "same optimisation algorithm", "same estimation algorithms", "same optimization algorithmsss", "same optimisation algorithmss", "same estimation algorithmss", "game optimization algorithmss", "stage optimization algorithmss", "qoe optimization algorithmss"
"attribute optimization algorithm" » "attribute optimization algorithms", "attribute optimisation algorithm", "attribute estimation algorithm", "attributed optimization algorithm", "attributes optimization algorithm"

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

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