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 optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithm"

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 optimizer algorithmssss") or ("modified parameter optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimizer algorithmssss") OR ("modified parameter optimization algorithm")).
• Removing quotes may allow a broader search: (( modified objective optimizer algorithmssss ) or ( modified parameter optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimizer algorithmssss") or ("modified parameter optimization algorithm"))*.
