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

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