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