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

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimization algorithm\") OR (\"modified caging optimization algorithmss\"))~".
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) OR ( modified caging optimization algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithm") OR ("modified caging optimization algorithmss"))*.
