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

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 objective optimisation algorithm") OR ("modified response estimation algorithmss"))~.
• Removing quotes may allow a broader search: (( modified objective optimisation algorithm ) or ( modified response estimation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithm") or ("modified response estimation algorithmss"))*.
