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

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 optimization algorithm\") OR (\"modified parameters optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( designed network optimization algorithm ) OR ( modified parameters optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("designed network optimization algorithm") OR ("modified parameters optimization algorithms"))*.
