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