Perhaps you should try some spelling variations:
"modified aging optimization algorithms" » "modified aging optimisation algorithm", "modified aging estimation algorithms", "modified aging estimation algorithm", "modified aging optimisation algorithms", "modified aging estimation algorithmss", "modified staffing optimization algorithms", "modified game optimization algorithms", "modified caging optimization algorithms"
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimisation algorithm", "modified objective estimation algorithm", "modified objective estimation algorithms"

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 aging optimization algorithms") OR ("modified objective optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified aging optimization algorithms ) or ( modified objective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified aging optimization algorithms") or ("modified objective optimization algorithm"))*.
