Perhaps you should try some spelling variations:
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"
"powder using methods algorithm" » "powder nursing methods algorithm", "powder making methods algorithm", "powder counting methods algorithm", "code using methods algorithm", "boiler using methods algorithm", "model using methods 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 objective optimisation algorithm") OR ("powder using methods algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective optimisation algorithm ) or ( powder using methods algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithm") or ("powder using methods algorithm"))*.
