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