Perhaps you should try some spelling variations:
"modified notion estimation algorithmss" » "modified notion estimation algorithms", "modified notion estimation algorithm", "modified notion optimization algorithms", "modified motion estimation algorithmss"
"modified passive solution algorithm" » "modified passive evolution algorithm", "modified passive convolution algorithms", "modified passive evolutionary algorithm", "modified adaptive solution algorithm", "modified positive solutions algorithm", "modified saline solution algorithm"

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

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