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

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("defined network optimization algorithms") or ("modified stochastic configuration algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("defined network optimization algorithms") OR ("modified stochastic configuration algorithm")).
• Removing quotes may allow a broader search: (( defined network optimization algorithms ) or ( modified stochastic configuration algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("defined network optimization algorithms") or ("modified stochastic configuration algorithm"))*.
