Perhaps you should try some spelling variations:
"modified allocation optimization algorithms" » "modified allocation optimisation algorithm", "modified allocation estimation algorithms", "modified allocation estimation algorithm", "modified location optimization algorithms"
"modified response estimation algorithmss" » "modified response estimation algorithms", "modified response estimation algorithm", "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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified response estimation algorithmss") or ("modified allocation optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified response estimation algorithmss") OR ("modified allocation optimization algorithms")).
• Removing quotes may allow a broader search: (( modified response estimation algorithmss ) or ( modified allocation optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified response estimation algorithmss") or ("modified allocation optimization algorithms"))*.
