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