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