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