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