Perhaps you should try some spelling variations:
"modified stochastic optimization algorithms" » "modified stochastic estimation algorithms", "modified stochastic estimation algorithm", "modified stochastic optimized algorithms"
"modified response optimisation algorithm" » "modified response estimation algorithm", "modified response estimation algorithms", "modified response optimization algorithm"

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 stochastic optimization algorithms") or ("modified response optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified stochastic optimization algorithms") OR ("modified response optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified stochastic optimization algorithms ) or ( modified response optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic optimization algorithms") or ("modified response optimisation algorithm"))*.
