Perhaps you should try some spelling variations:
"modified objective optimization algorithmsss" » "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective optimization algorithmssss", "modified objective optimisation algorithmsss", "modified objective estimation algorithmsss", "modified multiobjective optimization algorithmsss"
"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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified caging optimization algorithm") or ("modified objective optimization algorithmsss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified caging optimization algorithm") OR ("modified objective optimization algorithmsss")).
• Removing quotes may allow a broader search: (( modified caging optimization algorithm ) or ( modified objective optimization algorithmsss )).
• Adding a wildcard symbol may retrieve word variants: (("modified caging optimization algorithm") or ("modified objective optimization algorithmsss"))*.
