Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithm", "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"
"modified changing optimized algorithms" » "modified changing optimized algorithm", "modified changing optimizer algorithms", "modified changing optimization algorithms", "modified choosing optimizer algorithms", "modified caging optimized algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified changing optimized algorithms") or ("modified multiobjective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified changing optimized algorithms") OR ("modified multiobjective optimisation algorithm"))*.
• Removing quotes may allow a broader search: (( modified changing optimized algorithms ) or ( modified multiobjective optimisation algorithm ))*.
