Perhaps you should try some spelling variations:
"modified multiobjective approximation algorithms" » "modified multiobjective optimization 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: (("boiler using method algorithm") OR ("modified multiobjective approximation algorithms"))~.
• Removing quotes may allow a broader search: (( boiler using method algorithm ) or ( modified multiobjective approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("boiler using method algorithm") or ("modified multiobjective approximation algorithms"))*.
