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