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