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