Perhaps you should try some spelling variations:
"modified learning convolution algorithms" » "modified learning evolution algorithm", "modified learning solution algorithm", "mobile learning convolution algorithms", "modified caging convolution algorithms"
"modified objective solution algorithms" » "modified objective solution algorithm", "modified objective evolution algorithm", "modified objective estimation algorithms", "modified objective evolutionary algorithms", "modified objective allocation algorithms"

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 solution algorithms\") OR (\"modified learning convolution algorithms\"))~".
• Removing quotes may allow a broader search: (( modified objective solution algorithms ) OR ( modified learning convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective solution algorithms") OR ("modified learning convolution algorithms"))*.
