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", "designed network optimisation algorithm"
"modified static approximation algorithms" » "modified time approximation 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 algorithm\") OR (\"modified static approximation algorithms\"))~".
• Removing quotes may allow a broader search: (( defined network optimisation algorithm ) OR ( modified static approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("defined network optimisation algorithm") OR ("modified static approximation algorithms"))*.
