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