Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithmssss" » "modified multiobjective optimization algorithmssss", "modified multiobjective optimizer algorithms", "modified multiobjective optimized algorithms"
"modified parameter optimized algorithm" » "modified parameter optimization algorithm", "modified parameter optimized algorithms", "modified parameter optimizer algorithms"

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