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