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

You may be able to get more results by adjusting your search query.

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