Perhaps you should try some spelling variations:
"modified caging optimization algorithm" » "modified caging optimization algorithms", "modified caging optimisation algorithm", "modified caging estimation algorithm", "modified staffing optimization algorithm"
"modified learning method algorithm" » "mobile learning method algorithm", "modified learning mom algorithm", "modified learning methods algorithm", "modified graining methods algorithm", "modified learning emotion 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 learning method algorithm\") OR (\"modified caging optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified learning method algorithm ) OR ( modified caging optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified learning method algorithm") OR ("modified caging optimization algorithm"))*.
