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

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