Perhaps you should try some spelling variations:
"designed network optimisation algorithms" » "designed network optimisation algorithm", "designed network estimation algorithms", "designed network estimation algorithm", "designed network optimization algorithms", "defined network optimisation algorithms"
"modified allocation optimization algorithms" » "modified allocation optimisation algorithm", "modified allocation estimation algorithms", "modified allocation estimation algorithm", "modified location optimization algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("designed network optimisation algorithms") OR ("modified allocation optimization algorithms"))~.
• Removing quotes may allow a broader search: (( designed network optimisation algorithms ) or ( modified allocation optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("designed network optimisation algorithms") or ("modified allocation optimization algorithms"))*.
