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