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