Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified static estimation algorithmss" » "modified static estimation algorithms", "modified static optimization algorithms", "modified static optimization algorithmss"

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 static estimation algorithmss") OR ("modified multiobjective estimation algorithm"))~.
• Removing quotes may allow a broader search: (( modified static estimation algorithmss ) or ( modified multiobjective estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified static estimation algorithmss") or ("modified multiobjective estimation algorithm"))*.
