Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"modified caging methods algorithm" » "modified making methods algorithm", "modified learning methods algorithm", "modified counting methods 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 multiobjective optimizer algorithms") or ("modified caging methods algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimizer algorithms") OR ("modified caging methods algorithm"))*.
• Removing quotes may allow a broader search: (( modified multiobjective optimizer algorithms ) or ( modified caging methods algorithm ))*.
