Perhaps you should try some spelling variations:
"modified stochastic configuration algorithm" » "modified stochastic optimization algorithm"
"modified notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified motion estimation algorithms"

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

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