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

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