Perhaps you should try some spelling variations:
"modified stochastic configuration algorithm" » "modified stochastic optimization algorithm"
"modified objective optimisation algorithms" » "modified objective optimisation algorithm", "modified objective optimization algorithms", "modified objective estimation algorithms", "modified multiobjective 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: (("modified objective optimisation algorithms") or ("modified stochastic configuration algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimisation algorithms") OR ("modified stochastic configuration algorithm")).
• Removing quotes may allow a broader search: (( modified objective optimisation algorithms ) or ( modified stochastic configuration algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithms") or ("modified stochastic configuration algorithm"))*.
