Perhaps you should try some spelling variations:
"modified make optimization algorithmss" » "modified make optimization algorithms", "modified make optimisation algorithm", "modified make estimation algorithm", "modified market optimization algorithmss", "modified game optimization algorithmss", "modified stage optimization algorithmss", "modified male optimization algorithmss"
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation algorithms"

You may be able to get more results by adjusting your search query.

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