Perhaps you should try some spelling variations:
"modified static optimization algorithm" » "modified static optimization algorithms", "modified static optimisation algorithm", "modified static estimation algorithm", "modified stage optimization algorithm", "modified stochastic optimization algorithm", "modified staffing optimization algorithm"
"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 static optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified response estimation algorithms ) or ( modified static optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified response estimation algorithms") or ("modified static optimization algorithm"))*.
