Perhaps you should try some spelling variations:
"modified parameters estimation algorithmssss" » "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameter estimation algorithmssss", "modified parameter estimates algorithmssss", "modified parameter optimization algorithmssss"
"modified network optimisation algorithm" » "modified network optimization algorithms", "modified network estimation algorithm", "modified network estimation algorithms", "modified network optimization algorithm", "certified network optimisation algorithm", "defined network optimisation algorithm", "modified near optimisation 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 parameters estimation algorithmssss") OR ("modified network optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameters estimation algorithmssss\") OR (\"modified network optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified parameters estimation algorithmssss ) OR ( modified network optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters estimation algorithmssss") OR ("modified network optimisation algorithm"))*.
