Perhaps you should try some spelling variations:
"designed network estimation algorithmssss" » "designed network estimation algorithms", "designed network estimation algorithm", "designed network optimization algorithmssss", "defined network estimation algorithmssss"
"modified parameter optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimation algorithms"

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 estimation algorithmssss") OR ("modified parameter optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"designed network estimation algorithmssss\") OR (\"modified parameter optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( designed network estimation algorithmssss ) OR ( modified parameter optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("designed network estimation algorithmssss") OR ("modified parameter optimisation algorithm"))*.
