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