Perhaps you should try some spelling variations:
"modified parameters estimation algorithmsss" » "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameter estimation algorithmsss", "modified parameter estimates algorithmsss", "modified parameter optimization algorithmsss"
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"

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

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