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