Perhaps you should try some spelling variations:
"modified notion estimation algorithmsss" » "modified notion estimation algorithm", "modified notion estimation algorithmss", "modified notion optimization algorithmsss", "modified notion optimisation algorithmss", "modified motion estimation algorithmsss"
"modified parameters estimation algorithms" » "modified parameter estimation algorithms", "modified parameter estimates algorithms", "modified parameter optimization algorithms", "modified parameters estimation algorithm", "modified parameters optimization algorithms", "modified parameters optimisation 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: (("modified notion estimation algorithmsss") or ("modified parameters estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified notion estimation algorithmsss") OR ("modified parameters estimation algorithms")).
• Removing quotes may allow a broader search: (( modified notion estimation algorithmsss ) or ( modified parameters estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified notion estimation algorithmsss") or ("modified parameters estimation algorithms"))*.
