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