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"
"designed network optimization algorithm" » "designed network optimization algorithms", "designed network optimisation algorithm", "designed network estimation algorithm", "defined network 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: (("designed network optimization algorithm") or ("modified parameters estimation algorithmssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("designed network optimization algorithm") OR ("modified parameters estimation algorithmssss")).
• Removing quotes may allow a broader search: (( designed network optimization algorithm ) or ( modified parameters estimation algorithmssss )).
• Adding a wildcard symbol may retrieve word variants: (("designed network optimization algorithm") or ("modified parameters estimation algorithmssss"))*.
