Perhaps you should try some spelling variations:
"modified objective optimization algorithmsssss" » "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective optimization algorithmssssss", "modified objective optimisation algorithmsssss", "modified objective estimation algorithmsssss", "modified multiobjective optimization algorithmsssss"
"modified robust optimization algorithm" » "modified robust optimization algorithms", "modified robust optimisation algorithm", "modified robust estimation 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 robust optimization algorithm") OR ("modified objective optimization algorithmsssss"))~.
• Removing quotes may allow a broader search: (( modified robust optimization algorithm ) or ( modified objective optimization algorithmsssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified robust optimization algorithm") or ("modified objective optimization algorithmsssss"))*.
