Perhaps you should try some spelling variations:
"modified notion optimisation algorithms" » "modified notion optimisation algorithm", "modified notion optimization algorithms", "modified notion estimation algorithm", "modified network optimization algorithms"
"modified response estimation algorithms" » "modified response estimation algorithm", "modified response optimization algorithms", "modified response optimisation algorithm", "modified pose estimation algorithms", "modified response association algorithms"

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

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