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