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

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