Perhaps you should try some spelling variations:
"defined network optimization algorithms" » "defined network optimisation algorithm", "defined network estimation algorithms", "defined network estimation algorithm", "designed network optimization algorithms"
"modified parameter optimized algorithmss" » "modified parameter optimized algorithms", "modified parameter optimized algorithm", "modified parameter optimizer algorithms", "modified parameter optimization 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: "((\"defined network optimization algorithms\") OR (\"modified parameter optimized algorithmss\"))~".
• Removing quotes may allow a broader search: (( defined network optimization algorithms ) OR ( modified parameter optimized algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("defined network optimization algorithms") OR ("modified parameter optimized algorithmss"))*.
