Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"modified four evolution algorithm" » "modified four solution algorithm", "modified four evolutionary algorithm", "modified four convolution algorithms", "modified co evolution algorithm", "modified flour solution algorithm", "modified near evolution 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 four evolution algorithm") or ("modified multiobjective optimized algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified four evolution algorithm") OR ("modified multiobjective optimized algorithm")).
• Removing quotes may allow a broader search: (( modified four evolution algorithm ) or ( modified multiobjective optimized algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified four evolution algorithm") or ("modified multiobjective optimized algorithm"))*.
