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 static optimization algorithm" » "modified static optimization algorithms", "modified static estimation algorithm", "modified static estimation algorithms", "modified stage optimization algorithm", "modified stochastic optimization algorithm", "modified staffing optimization algorithm"

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 static optimization algorithm"))~.
• Removing quotes may allow a broader search: (( designed network optimisation algorithm ) or ( modified static optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("designed network optimisation algorithm") or ("modified static optimization algorithm"))*.
