Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"boiler using method algorithm" » "boiler using mom algorithm", "powder using method algorithm", "boiler nursing methods algorithm", "boiler focusing method algorithm", "boiler using metal algorithm"

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

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