Perhaps you should try some spelling variations:
"modified objective optimizer algorithmssss" » "modified objective optimizer algorithms", "modified objective optimized algorithms", "modified objective optimized algorithm", "modified objective optimal algorithmssss", "modified objective optimization algorithmssss"
"modified parameter estimation algorithm" » "modified parameter estimates algorithm", "modified parameter optimization algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified parameter estimation algorithm") or ("modified objective optimizer algorithmssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameter estimation algorithm") OR ("modified objective optimizer algorithmssss"))*.
• Removing quotes may allow a broader search: (( modified parameter estimation algorithm ) or ( modified objective optimizer algorithmssss ))*.
